Both my iPad 2 and iPhone 4S started getting stuck checking mail a few days ago and its draining my battery in just a few hours on the phone and a day on the iPad. I have a yahoo account and exchange account i have deleted and re-set up and have removed both tried one it keeps getting stuck at connecting to mail. It's made my phone and iPad worthless. More worried about the phone. I have had every iPhone and have never had a problem like this. I did a factory restore as new and a factory restore from back up the problem stays. I see discussion in the forums but no solution. Thanks!!
