HTC Aria

After the Motorola Backflip, it is the second Android device for AT&T Wireless, and it was better received by critics than its predecessor.

[1] AT&T Wireless faced criticism for its inability to download .apk files—Android applications outside of the Android Market.

The update (version 3.0.5372) gave the ability to side-load non-market applications to the device.

The official Android 2.2 update prevents rooting the device,[9] disallowing loading of custom ROMs.

Root access can be restored through a multi-step process that requires the device to be connected to a computer.
