Ok having a weird issue the last 3-4 days. Will use my phone at home. Email internet work fine on the wifi. I leave the house and email/internet no longer work. Cant bring up websites and get retrieve email. So I tried shutting off and turning back on then it works fine, connects to ATT for data and email. Same thing happened again today. And again I needed to shut off the phone turn it back on before i could receive email/data. I could still text and talk on phone which is really weird. BUt not internet from safari and no email. Anyone else have a similar issue?? This is on a 4S and it worked fine until the last few days.
