My wireless connection has worked flawlessly forever but the other day it started giving me trouble. Itsays it is connected but won't download data. The only way to get it to work again is to take my email off push and then turn airplane mode on and off. The connection will then work for about 20 minutes maybe and then I have to do it again. My wifes phone works fine so I know it's not a network problem. Anyone else had this same issue. I'm using 3.1.2 software and it is jailbroke using blackrain.
