    Hello World, my first post on macrumors

    I tried searching but most of the information was not in recent time, so figured to post a new thread.

    I bought a used 3GS 8GB yesterday from a person. The phone is unlocked and jailbroken.

    Here is the relevant information:

    Version: 4.3.2 (8H7)

    Model: MC640LL

    Modem Firmware (baseband, i think): 06.15.00

    Currently I am using it with T-Mobile, so I know it is unlocked properly.

    My question is....

    The phone has apps and settings from the previous user. I want to 'reset' or 'restore' or something like that to remove all settings and content from previous user.

    If I go to Settings --> General --> Reset and perform a reset, will my phone still be usable with T-Mobile?

    Thank you all. Hope I provided enough info to answer.

    you need to restor with custom firmware, because of the 6.15.00 baseband.

    then jailbreak and install ultrasnow.

    hurry up because 4.3.3 was released and might not be jailbreakable.

    if you have SHSH for 4.3.2. or anything earlier, you will be OK.

    You need to make yourself a custom firmware first using pwnage tool. In pwnage tool select install cydia and select no baseband update.

    Then get redsn0w and put the phone in pwned DFU mode.

    Then you can do a option key plus click the restore button in itunes, browse to the custom restore you made and start your restore.

    When done the phone already has cydia loaded.
