I ordered a couple of IPhones last week for my wife and I, and they came in yesterday. And I've already got a problem with mine. It seems mine doesn't want me talking on the phone. Just about every phone call I received today seems to end when I answer the call. At first I thought it may be the sensor problem that I've read a little bit about, but I think I've ruled that out. I can lay the phone flat on the table, make a call to the phone, and try answering it as it lays on the table. And it ends the call as soon as I answer. Now this doesn't happen on EVERY call, but at least 90% of the time it does happen. Has anyone else experienced this problem?
