The HTC Dream was released in the US on 22 October 2008; in the UK on 30
October 2008; [5] and became available in other European countries including
Austria, Netherlands, and the Czech Republic in early 2009. [6] It was released
in Germany in February 2009 with a QWERTZ keyboard [7] and in France in
March 2009 with an AZERTY keyboard [8] . On 10 March 2009, it became
available in Poland as Era G1 under a local mobile brand affiliated with
T-Mobile. [9]
As of 2008, in the US, it was priced starting at $129.99 for new and existing
T-Mobile customers if purchased with a two-year T-Mobile voice and data
plan, and $399 without a contract. [10] Contrary to claims made by T-Mobile
representatives, the handset does not need the data plan to work. The Dream
comes in black, bronze (formerly called "brown"; except in the UK), or
white. [11]
On 23 April 2009, T-Mobile USA announced it had sold one million G1s since
the device's launch. [12]
On 5 February 2009, the phone was released through Optus in Australia, as the
HTC Dream. [13] On 21 February 2009, Singapore became the first country in
Asia to introduce the phone. It was sold by SingTel between $38 – $238 under
various contracts. [14] [15] Telefónica also launched a version of the phone in
Spain on 20 April 2009 [16][17] with slightly modified control buttons. [18]
On June 2, 2009 it was released through Rogers Wireless in Canada as the
HTC Dream. This variant, DREA210, supports the UMTS 850 / 1900 bands
and HSDPA up to 7.2Mbps for use on Rogers' 3G network. [19]

Display: 3.2 in (8.1 cm) TFT-LCD flat glass touch-sensitive HVGA
screen with 480 X 320 pixel resolution. The capacitive touchscreen
makes it impossible to use a standard stylus. Users can interact to bring
up or move content with a finger touch, tapping or touch-drag
motion. [20] The touchscreen hardware is capable of multitouch
gestures, but official release of Android (v1.0 to v1.6) available for the
G1 have this functionality disabled at the kernel level. Users can patch
the supplied version of Android, download a hacked version or update
to Android 2.0 or later to make use of the multi-touch screen. [21]

HTC Magic
CPU: The MSM7201A is an ARM-based, dual-core [22] CPU/GPU from Qualcomm and contains many built-in features,
including 3G and a GPU capable of up to 4 million triangles/sec. It has hardware acceleration for Java, [23] but this does not
accelerate execution of Android applications, as they are targeted to the Dalvik VM, not the Java VM.
Keyboard: The HTC Dream has a sliding full 5 row QWERTY keyboard. It also comes with a set of 6 navigation buttons:
phone (green, black in UK) – make outbound calls, receive incoming calls, or open the dialer.
home (black) – displays home screen with shortcut icons for some applications and a drawer containing all
applications on the phone.
trackball – navigate among items on the screen or scroll in text fields.
back (black) – return to the previous screen.
phone (red, black in UK) – end currently active call or put phone into sleep mode.
menu (black) – display the contextual menu for the current screen.
a touchscreen keyboard is available as of Android 1.5. Note: this feature does not work on phones sold to be used
on the Rogers Wireless network [24] .
Side controls: A pair of volume buttons is located on the left side of the phone, and a camera button on the right side.
Audio: In place of a headphone jack, the Dream (like many HTC smartphones) has a mini-USB-compatible ExtUSB jack
[25][26] that carries audio signals alongside the regular USB signals, and can be converted with a dongle (now shipped with
the phone) to support any standard 3.5 mm headphone. The standard headset includes a clip-on microphone and call
answer/hangup button. The Dream supports audio files in MP3, AAC, AAC+, WMA, MPEG4, WAV, MIDI, and Ogg
formats. [27]
Camera: The HTC Dream has a 3.2-megapixel camera with autofocus functionality. [28]
Video: The Dream can play H.264, streaming, 3GPP, MPEG4, and 3GP files. [27] There is no light ("flash") for the camera
in low light conditions. Video recording and uploading to YouTube is available as of Android 1.5. Recording resolution
352x288 H.263 3GP Mono sound @ 8 kHz.
Storage: The HTC Dream has a microSD card slot and comes with a 1GB memory card (2GB in the UK, Germany and
Canada). It has been confirmed to work with capacities up to 16GB, and may work with even larger cards. [29] When the
USB cable is connected to a computer, this computer can access the card without removing it from the HTC Dream. The
phone can access media files arranged in folders, but the folders have to be created from a third-party file management
application or from a computer or a third-party file-manager program on the phone.
Battery: The HTC Dream has a user-replaceable, 3.7V, 1150 mAh (4.25Whr) rechargeable lithium ion battery, which is
advertised to offer up to 130 hours of standby power.
Orientation and location: The HTC Dream provides an accelerometer for detecting movement and determining which
direction is 'Up'. It also has a digital compass, giving it complete orientation data. The Dream includes a GPS receiver for
fine-grained positioning, and can use cellular or wifi networks for coarse-grained positioning.
Case: Three different colors are available: black, bronze, white.
Connectivity: Wi-Fi (802.11b/g) using a Texas Instruments WL1251B chipset; Bluetooth 2.0+EDR via Texas Instruments
BRF6300; ExtUSB with an SMSC USB3316 chipset; standalone GPS and A-GPS; Quad band GSM 850/900/1800/1900
MHz and GPRS/EDGE, plus Dual band UMTS Bands I and IV (1700 & 2100 MHz) and HSDPA/HSUPA (in US/Europe)
at 7.2/2 Mbit/s using the Qualcomm RTR6285 chipset
The HTC Dream runs the Android Operating System. Several applications that come installed with this device are:
Full HTML web browser powered by the WebKit rendering engine; it allows a maximum of 8 windows (but not multiple
windows in the same screen, except in reduced size for the purpose of selecting one)
Gmail

In the United States, the carrier-subsidized firmware for the G1 also comes with an application for accessing the Amazon MP3
music store, which allows users to browse and legally purchase DRM-free songs; however, in developer firmwares this application
is not included. [30] More applications can be obtained through the Android Market application or directly through developers.
Documents in Google Docs can be viewed, but not edited. However, spreadsheets in Google Docs (including the texts in them)
can be edited. [31][32]
Updating
The Dream firmware can be updated by flashing from an image stored on the microSD card. [33] These images are
cryptographically signed by either the phone manufacturer or network carrier. [34] Along with other features, support for widgets
were introduced through updates. [35] As of Friday, December 18, 2009, HTC (http://www.htc.com) and Rogers Wireless
(http://www.rogers.com) have both stated that they will not support Non-Google branded HTC Magic and HTC Dream phones
past Android Version 1.5. HTC changed the content of its website to reflect this (Magic (http://www.htc.com/ca/support/magicrogers/help/system-and-upgrade)
), (Dream (http://www.htc.com/ca/support/dream-rogers/help/system-and-upgrade) ), and Rogers
Wireless notified the Android community by a post (http://androidforums.com/rogers/10647-rogers-dream-1-6-update-
11.html#post197520) in AndroidForums.
When it comes to receiving the latest Android OS updates, the Dream has been left behind. For example, on T-Mobile, the Dream
is stuck at Android version 1.6, and it is unlikely that it will be updated [36] .
On December 5, 2008, Google announced the Android Dev Phone 1, a hardware unlocked version of the HTC Dream. With this
version, the user is not only able to use any GSM/UMTS carrier, but also has complete superuser access to the device which is not
found in the retail version. The advantages to this version is that it gives full access to the internal files of the phone, in particular
changing and re-flashing the bootloader and operating system. [37] This version also has pre-installed utilities to aid in the
development of Android apps. This version is sold for US$399 and is only available to registered members of the Android
community which is open to all developers for a US$25 fee. [38] Depending on the country, the additional shipping charges (which
include tariff and tax) may amount to a substantial fraction of the base price; for example, shipping charges to United Kingdom are
$128.25, to Germany are US$134.31 and to Poland US$162.
Upon the launch of the T-Mobile G1, one concern among developers was that limitations were present in its build of Android that
blocked superuser access to the phone. However, a severe vulnerability was soon discovered in early versions of the firmware —
everything typed into the phone's keyboard was being interpreted as commands in a root shell. [39] By using telnetd to exploit this,
users could flash a modified image with root access. This process, dubbed "rooting" by the community, [40] allows users to gain
superuser access and perform actions previously impossible without root access, such as installing custom builds of Android,
running Debian, [41] installing custom themes, and enabling ad-hoc Wi-Fi tethering. Although Google and T-Mobile were quick to
patch this vulnerability with update RC30, a ROM from HTC was later leaked allowing users to downgrade to an older firmware
with the bug. [42] The Android Dev Phone 1 comes with superuser access officially integrated into its firmware, allowing native
code and custom kernels to be run without any special hacks. [43]
Rooting also allows the use of modified images to run on the G1 through the original vulnerability. For example, a leaked HTC
Magic (Android 1.5) OS was modified to run on the device. Before the official Android 1.5 build for the HTC Dream was released
(which included these features), this enabled functionality such as video recording, stereo Bluetooth and an on-screen keyboard.
One popular unofficial firmware release for the Dream/G1 is CyanogenMod which (as of June 19, 2010) is at version 5.0.8. [44] It

is almost a full port of Android 2.1 to the Dream/G1, including almost all of the features available in the Nexus One and Motorola
Droid versions of CyanogenMod. The only major features missing are Live Wallpapers and Gallery3D, which were not included
due to the limited hardware of the Dream.
Following the disclosure of a root exploit, Jay Freeman released details of how to run Android and ARM Debian Linux together
on the Dream. [45]
