I get one bar or "No Service". I didn't notice if this happened before I installed any tweaks, so I don't know what's causing this issue. I just updated from iOS 6.1 and everything was working find (besides a few crashes...) Now 3G isn't working. I make calls, send texts, etc. I usually have 3-4 bars sitting in this exact spot at my desk. Perhaps iOS 6.1.2 is causing the issue, and I didn't notice prior to jailbreaking. Any ideas???
