There are now Android 2.2 Firmware Over The Air (FOTA) updates available for the HTC Legend and HTC Wildfire. This updates the Android OS on the two devices to FroYo, the same as the HTC Desire which received its update earlier in the year.
The updates can be accessed from the Support section of the HTC website. As always we would advise backing up any important data before applying the update.
Firmware Update Instructions:
Your phone will receive a notification of FOTA update when it is made available. Simply press OK to accept the update via a data connection such as Wi-Fi or GPRS/3G. After installing the update, you can confirm a successful update by confirming the Build number (From the Home Screen go to MENU> Settings> About Phone> Software Information> Build number). The new Build number after the update will be 2.22.405.1. Update: Android 2.2 update. Note：Please back up your data first before upgrading your phone. We recommend using a free Wi-Fi hotspot or an unlimited data plan to apply this update. If not, standard data connection charges may apply.
