Early July, HTC promised the long awaited HTC Desire Android 2.3/Gingerbread upgrade for end of July and now, HTC has released something which seems to be the promised update. However, it neither comes over the air nor is it free from footnotes. As a matter of fact, HTC says that the Desire upgrade is only recommended for expert users who want to experience Android 2.3 and understand the limitations which apply to this update. Due to memory constraints several applications have been removed from this update and HTC is only offering the ROM upgrade utility (RUU) for customers to download. Furthermore HTC says that this Rom update is for development only and not for general public use.
Since it's flashed the traditional way - from a PC - this ROM will erase all previous customizations, including any messages, E-Mail, contacts and other personal information. However, the SD card will not be erased or modified.
The major changes in this update include that all customizations, including operator applications, will be removed; all wallpapers, except the default wallpaper, will be removed and placed online on the HTC Developer website;s everal HTC applications will be removed and placed online on the HTC Developer website; the official Facebook application will be removed and is downloadable on the Android Market.
While it makes sense that upgrades to non-authorized phones may result in loss of functionality it's unclear what HTC mean with "certain functions may no longer be usable after re-flashing the ROM, including but not limited to MMS and SMS"? Is this just a general warning that it could - very theoretically - happen or is HTC expecting that it happens on most of the flashed Desires?
Anyway, it looks like a couple of HTC partners aren't too satisfied with the Android 2.3 build and there fore, due to concerns raised from partners, the following regional variants are not-compatible with this upgrade: Germany (Deutsch Telekom), North America, South America, South Korea, and Japan.
However, if you still feel that you want to upgrade your HTC Desire to Android 2.3 now, you can get the 161 MB download from HTC's Developer site.
