Just wanted to get confirmation on something. I'm on AT&T and my phone is jailbroken on 5.0.1 with the 1.59.00 bb (I preserved the bb for resale value and just in case I actually need to unlock at some point). I've also had ultrasn0w installed strictly to fix the signal strength issue, but I've found ultrasn0w to be buggy and I want to get rid of it. Now that AT&T has officially unlocked my iphone 4, I no longer need to stay on the 1.59.00 bb; however, it seems like my only option is to update to stock 5.1 to allow my bb to update and then go back to 5.0.1 via a custom ipsw (I do have 5.0.1 blobs saved) - that will leave me on 5.0.1 with the latest bb. Will that reintroduce the signal strength display issue that was caused by having mismatched firmware and bb versions? My preference would be to get to 5.0.1 with whatever bb came with that firmware version but that seems to be impossible. What is my best option if I want my signal strength to display correctly but don't want to keep ultrasn0w installed?
