I recently made a thread but seeing as how it fell into obscurity and I have found some new things out about the situation. Anyway, my phone would randomly lose 3g and I wouldn't be able to load anything untill I reset my network setting. I took it to apple and they gave me a new phone and and even went to AT&T and got a new sim, still no dice. I also haven't been able to send mms. Now I have just found out that I can send mms and I don't lose Internet if I'm on edge only with 3g off. What could be causing this type of problem?
