    Hello Everyone,

    Long time listener....First Time Caller.

    I just upgraded the rid and iphones to 4s. I have a friend who is on T-Mo and would like to purchase one of the 3g's and use it.

    Can somebody give me some guidence on what needs to be done....never had to unlock as I am on AT&T.

    What version should I go with...the phones currently have 3.1.3. Can I upgrade him to 4.0 and then jailbreak and unlock?

    Also, do i just take his sim out of his current t-mo phone and drop it in my iphone? What about a data plan on t-mo?

    Thanks for any guidence on the best course of action.

    Since it's a 3G, you should be able to upgrade it to iOS 4.0, use the redsn0w beta from dev team to jailbreak, then install ultrasn0w 0.93 to unlock.

    Once ultrasn0w is installed, you insert the T-Mobile SIM and you might need to reboot the phone. As for Data plans, you'd have to check their website for plans that would work for smart phones. :)

    whats with all these newbs answering.. lol


    Jailbreak iPHone 3G on 4.0.1

    Step 1 : Connect your iPhone 3G to your computer and let iTunes update it to 4.0.1
    Step 2 : Download Redsn0w 0.9.5b5-5 and the 4.0 firmware located here and save it to your desktop. Now fire Redsn0w up it will have a browse button, click that button.
    Step 3 : Now click on the 4.0 firmware you just downloaded.
    Step 4 : Next Click the checkbox for Cydia and click Next
    Step 5 : Power off your iPhone 3G but leave it plugged in, then click Next
    Step 6 : Put the iPhone into DFU mode, you will know when this happens because redsn0w will start the install.

    Now sit back and wait for about 5 minutes your iPhone will then reboot and be jailbroken. You can now unlock.

    Step 7: Cry as your 3G iPhone slows down and lags all the time. If you have a 3G iPhone instead of a 3GS, do NOT update to 4.01!!! :eek:
