Hello, I've been having problem recently (within the last month) with my iPhone 4S and microcell from AT&T and it seems to have gotten a lot worse since I installed the new update a couple of days ago. The problem is that it will connect to the Microcell, I'll have 5 bars, it will say M-Cell but it won't connect to the cell service...meaning there will be no little 4G symbol next to the M-cell. Wireless works fine, etc. It used to be that everything would connect no problem upon returning home (where we have NO cell service) but now I have to turn off my phone and turn it back on to get cell service and sometimes that doesn't even work. Any ideas?
