It was sold by many different vendors under the names of O2 xda Exec, Orange SPV M5000, Dopod 900, Qtek 9000, T-Mobile MDA Pro, I-mate JasJar, Vodafone v1640, Vodafone VPA IV, E-Plus PDA IV, etc. Despite all the different model names and housing appearance, they all have identical hardware specifications with small differences in the external color and branding.
The most notable feature of the HTC Universal is its 180-degree swivel screen, allowing a quick swap between portrait mode and landscape mode. The included version of Windows Mobile 5.0 automatically adjusts screen orientation to match screen orientation.
SIM lock
Most network-supplied versions of the Universal are shipped SIM-locked, with the O2 XDA Exec being a notable exception. However, a free SIM unlocking tool was released.[1] This process involves flashing a new Radio ROM onto the device, and it may invalidate the device's warranty.
Memory expansion:SDIO/MMC card slot (officially without SDHC, with maximum capacity supported being 4GB, but there is unofficial SDHC support from xda-developers– SDHC cards are accepted with Windows Mobile 6.1 or higher and there is another unofficial update to Windows Mobile 5 that allows the use of SDXC cards up to 64GB.[citation needed])
Standard battery capacity: 1620 mAh (included; battery is removable)
Charging: Mini USB (also used for data transfer)
Extended batteries
There have been many high-capacity "extended" batteries available for the HTC Universal. 2600mAh, 3150mAh, 3200mAh, 3800mAh, 4800mAh and even 5200mAh models have been sold by various retailers, which allow the device to run for an extended period of time. Similarly to most expandable battery technology, they make the device heavier. The 3800 mAh battery is a Lithium-Ion battery with model number PU16B manufactured by Dynapack International Technology Corporation in Taiwan.
Unofficial extensions
Registry editing and ROM reflashing can be used to modify the device's included software to add such features as:
Wireless G (802.11g) connectivity. This only allows the device to communicate using the 802.11g protocol instead of 802.11b, it does not give a speed increase beyond 11 Mbit. However, numerous online sources now say this no longer works.[2][3]
Full VGA (640 x 480 resolution) graphics, as opposed to the "QVGA (320 x 240) emulation/compatibility mode" which the Universal runs in by default. The two main downsides to this are that some software cannot handle "true VGA" mode, which usually results in corrupted graphics, and that it can be quite difficult to see (and use a stylus with) such small screen elements as text.
Emulation and mapping of additional keys not found on the Universal native keyboard, such as CTRL and ALT.
Support for SDHC cards. 8 GB, 16 GB and 32 GB cards have been tested successfully. This is only made possible via a third-party hacked driver.
128 MB of RAM. It is possible to replace 64 MB memory modules with 128 MB one. It can be only used with 128 MB enabled ROMs but it makes more space for running applications.
Linux
It is possible to install a custom version of Linux on the HTC Universal. Despite the lack of cooperation by HTC (and most other smartphone/PPC manufacturers for that matter), drivers for most of the device's components are functional (the two cameras and the flash ROM being the only significant exceptions). It is possible to run various handheld Linux distributions on the Universal, though application support is in its infancy.
Windows Mobile 6 (Crossbow)
There are numerous "unofficial" builds of Windows Mobile 6 (Crossbow) which have been made to run on this device, and now even some tools that allow users to create their own custom WM6 ROM images (a process commonly known by the term "cooking ROMs"). There is a community dedicated to improving these WM6 builds (and associated tools) on the Universal.
