my 2G is on 3.1.3 and Wifi is unstable, like sometimes it doesn't even recognize the home Wifi. I tried downgrading to 3.0, but it would just get stuck in "waiting for reboot" from Redsn0w app. Upgraded to 3.1.3 through Redsn0w as well.
Would anyone know what might be the problem?
P.S. Searched the forums already and couldn't find anything.
