This is the first real problem I've encountered with iOS 5 - SMS text messages. I can't seem to receive any, and I keep getting the same error that my mailbox is full and I need to delete messages before I get some. I've deleted almost all of them, and I still can't get any texts. However, I get all my iMessages just fine. Every time someone texts me, I have to delete some texts, turn off my phone, and boot it up again. Then their message will show up in my inbox, however, when I reply, I get the same error over and over again. It's a horrible never ending cycle. I've tried doing all sorts of research on this, but nothing came through. Has anyone else encountered this problem? If so, have you found any solutions? P.S. I have a genius bar appointment set up for Tuesday the 8th. I think some screw is loose on my camera, so I'm also going to bring this up to them while I'm there, although I'm pretty sure they will blame AT&T for this.
