    Hi there,

    I am using Mac pc with the pwnage tool to jb and unlock my iphone (base band 01.59.00). it works fine for few day then suddenly battery drain so fast. from 8 o'clock to 1, battery drained nearly 40% with standby. During the whole time I did not add or install any new apps at all. I google a notice that Redsn0wrc15 + may fix the battery problem. I'd like to restore and jb then unlock again with windows instead Mac.
    anyone please guide me how to use windows to jb without changing baseband.
    I did download:
    Tiny Umbrella

    what else do I need for jb and unlock ?

    Update: I just download the sn0wbreeze 2.7.3, and created a custom 4.3.3.ipsw, question is if I use itunes to restore this custom file, does the phone still can be unlocked or not? does it upgrade my baseband ? I haven't done jb and unlock using windows pc so I need abit info. before doing it

    sn0wbreeze will preserve your old baseband. Once you're done with sn0wbreeze custom 4.3.3.ipsw, just hold the Shift key and click Restore on iTunes and point it to your sn0wbreeze custom firmware.

    After you're done with Jailbreak, just install ultrasn0w via cydia and it will unlock your phone.
