Whenever I get an OTA, I always start by wiping the phone first, then installing the OTA to a clean device, then I wipe it again before I start installing anything. And not that bogus hard-reset: I'm hardcore so I go all out with the ##786# option. I've never had issues with an OTA before until now. I had (and still have) issues with the prox switch and the Power Saver icon, but once I turned off "Fastboot" under the Power settings and did a proper shutdown and restart, I haven't seen the Power Saver icon once. And I have restarted the phone a half dozen times since and still have yet to see it again.
