Ive searched everywhere and cant find anything specific but any of the 2.2 rom's that I've flashed have caused bad problems when the sync icon pops up and I assume that the phone is attempting to sync with google. What im not quite sure.
It occurs usually after a reboot and usually a couple minutes after it gets to the homepage when the sync icon pops up and within a couple of seconds the phone freezes and either requires a battery pull or eventually the phone will crash and reboot. When it does reboot after it crashed it strangely function better.
Ive tried to disable sync but even if I do that the phone will still attempt to sync and lock the phone up. Ive tried several different Roms ranging from stock, jrummy, and cyanogen 6 rc1 and have the same issue. I have tried wipe data and cache but I have not tried to fix permission cause the phone usually doesnt run long enough to do it until I get lucky for it to last. It also occurs from either fresh install or long
Currently on cyanogen 6 RC1
