Just saw this update notification on my HTC Desire when I woke up
this morning. Finally — Android 2.2 Froyo is now available on the
Desire.
The update is about 96MB in size and the upgrade takes around 20 to
30 minutes depending on your connection speed. I suggest doing this over
WiFi instead of 3G (the update can pause and continue later if you get
wonky connection so not a huge issue).
Android 2.2 Froyo seems more snappy on my HTC Desire afterwards. HTC also sent out this notice today.
