Hey all - thanks to helpful members like Applejuiced, I easily updated my iP4 to 5.1 while keeping the 1.59.00 BB (haven't JB yet - used custom NO_BB IPSW via Redsn0w, though). Everything is up & running, except I only have one bar of signal everywhere I go. Fortunately, it appears to be only cosmetic. I searched some old threads from Dec. and it appears that there were fixes - anyone have this issue on the current FW, & if so, what fixes are there available? Thanks, all!
