Thread: Queries on iPhone 3GS unlock and preserving baseband

  1. #1
    Default Queries on iPhone 3GS unlock and preserving baseband
    I am wanting to buy an used iPhone 3GS but whatever unlocked ones are available on craigslist / ebay.com seem to have their baseband updated to 6.15, the ipad baseband which breaks the GPS functionality.
    In this case, can i buy a AT&T locked iPhone, not updated to iOS 5 and unlock it myself PRESERVING the baseband so as not to break the GPS ?
    If yes then before buying the locked iPhone 3GS, what all things i need to check to ensure that i can preserve the baseband and also unlock and jailbreak it.

    good luck finding one that still have ios 4.0 or lower with unlockable baseband. when new ios version come out, people will update through itunes, only a small percentage that update but preserve the baseband.

    In that case i will only be able to get an unlocked and jailbroken with 6.15 baseband right ?
    Does GPS work in such iPhone 3GS with ipad baseband ?
    Will there be any baseband downgrade available ?

    The best and easy way are to find an iPhone 4 with fw 4.3.5 then restore iOS5 with preserve baseband.
    Now you can unlock it Gevey Sim
    Semi tether jailbreak
    keep your GPS working
