I have had the 4s since the release date.... Every since I got the phone I have had to get my emails manually no matter how I set it up...also everything has been very slow and delayed lately... When I usually sell an item on eBay I get a notification right away but now I get my notification hours later...when using the eBay app on my phone the pages won't load and I get message saying no data connection sometimes... The whole time my phone is showing full signal strength...I have owned every iPhone and have never seen this.... I'm wondering if this is a network issue or phone issue.. I'm with AT&T and I'm located in Maryland ... Anyone else having these problems ?
