Jailbreak/Unlock iPhone 3G's before I sell them?

[thegreatdivorce]

I have a couple 3G's that I need to get rid of. One is at 4.0 and seems fine, one is still at 3.1.3/4.26.08 and is also fine. Unless I'm missing something, I don't see any way to JB/unlock them on 4.2.1 without using the 6.15 baseband (and potentially lose GPS, etc.).

Should I just restore them, and sell locked/un-jailbroken? Can't make up my mind...

Well when I sold my 3G, a few days before I updated to 4.0 but it was so darn slow then I reverted back to 3.1.3. The speed of the phone is a good selling point and with 4.0 slowing it down so much, I felt that it would have been hard trying to sell it. If you don't want to go through that whole process, I believe you are fine. 4.0 is on baseband 1.59 which can be unlocked with ultrasn0w and the 3.1.3/4.26.08 can definitely be unlocked.

You can jailbreak your 4.0 iphone with jailbreakme.com and your good to go. Probably the easiest version to jailbreak in my opinion. Also, the iPhone is of much greater value when unlocked because people on different carriers can use them.

You have a few options:

You can jailbreak both by going to jailbreakme.com using safari on the phones. Once Cydia is installed, install the needed Cydia updates & install Ultrasn0w.

If you want to update the phones to 4.2.1 you will need to use PwnageTool to create custom firmware. This will update the firmware while leaving the basebands alone. Use itunes to restore to the custom firmwares and install Ultrasn0w.

Update to stock 4.2.1 and then use Redsn0w to jailbreak and change to the 6.15.00 iPad basebeand. Then install Ultrasn0w.
