After months of being really happy with 1.5, I ran with OTA 2.1 for about a week.... hated it! While I didn't see any outright bugs, the phone had hugely sluggish response, very poor battery life, etc. Finally decided to to the Factory Data Reset this morning, and voila - lovin' my Eris again. Things to note: Before Factory Data reset w/ 2.1 OTA: - Phone uptime and awake time were almost equal (not good) - Had the 50% without signal message - 'Android System' always listed as top user of battery usage (60-70%) - Even while idle, phone always felt 'warm' (like it was continually running a background process, as evidence by poor battery life) After Factory Data reset w/ 2.1 OTA: - Phone uptime and awake time now as expected (awaketime < uptime) - No more 50% signal message - Cell Standby and Phone Idle now top users of batter usage. - Phone now cool to the touch while idle One thing to note is even after the reset, I still had issues syncing Gmail contacts, and needed to delete the contacts cache. While I won't conjecture about root cause, I'm hoping Google and VZ learn from this experience, as much of this mucking about is *way* beyond what most 'normal' users would put up with. My wife loves her iPhone and just laughs at me dealing with all this c**p. Besides, I can't remember the last time *she* had to reboot her phone..
