I unrooted my phone using a 2.0.1 sbf. After booting, the phone immediately downloaded the 2.1-update1 OTA update. It is now sitting there and says that my system is up to date, even though I know there is a 2.2 OTA update available. I found a thread on here where someone just used a 2.2 sbf, but I'd imagine there has to be some other way to force the OTA update. Any suggestions?
