ok 2 things. 1. this is a beta for a reason. i would much prefer Apple to release it to devs first so they can deal with the bugs and provide feedback, rather than have people complain that Apple broke more than they fixed. now i'm gonna put this in bold, because the people that don't know this need to rehearse it and say it 10 times. 2. Apple FIXED the bars. the bars have been displayed incorrectly ever since the iPhone released. now the bars are displayed properly. this isn't supposed to fix the signal issue, it's just displaying the bars properly. that is all.
