    I have done this. It works...sort of. The signal bars don't change though. It's stuck at one bar all the time.

    My 3GS T-mo signal bars work good with the fixer.

    This does not work with 5.16.02, right? Is there any way to unlock this baseband?

    Use Redsn0w to upgrade to 6.15 or wait for an unlock that may never come out.

    Thanks....hmm...the 6.15 thing sounds kinda sketchy. I might have to buy another iphone than hasn't been upgraded. I just grabbed one that the owner had updated before selling. Too bad, it is in really great shape!

    Thanks OP, definitely cleared up some of my questions, including the confirmation that the unlock only supports 01.59 BB for iPhone4 :(

    Does anyone know if the guys are working on unlocking BBs like 03.10.01 and others? I was hoping/thinking that Musclenerd's been working on the new unlock as opposed to for those retaining the current unlock... :)

    But what's your actual signal strength (go to phone keypad, type *3001#12345#* and hit Call and look at the number in the upper left where the bars usually are)?
