I was wondering if anyone has experienced this and if anyone has a solution to it... I always sorta thought it was ATT but now I'm starting to think it's my iphone, and it's not the first time it's happened... this is my 2nd iPhone (it was replaced) and it still happens on this new one. Anway, the problem is that when I get a call coming in and my phone is "locked" and it says "slide to answer". Well I slide to answer and put it up to my ear to talk and the other end of the line is blank... no sound at all.. but it says that I'm connected with them. So I have to hang up and call them again. Anyone else experience this?
