    Since I am getting an iPhone 4, I am having my cousin in Israel help me sell my 3GS unlocked while I am there on vacation later this summer. I still have six days (including today) before I'll have the new phone, so I'm not exactly ready to wipe my 3GS today, but I want to make sure this is possible.

    Can I follow all of the "Downgrade" instructions in the sticky in this forum section but simply shift click restore to 3.1.2 while 3.1.2 is currently installed? I simply want to keep the 05.11.17 baseband so the blacksn0w unlock works, as this is the most important factor if I'm going to sell my phone to an international customer.

    If this works, I plan to restore to 3.1.2, keep the 05.11.17 baseband, and use Spirit to jailbreak (and then install blacksn0w).

    Yes it will work and your baseband will be preserved but make sure you "shift restore"/downgrade to 3.1.2 not 3.1.3 or ur screwed

    Yeah, I downloaded the 3.1.2 files and made copies of my hosts file (one with the edits and one without) in preparation. As soon as my new phone comes, I want to be able to sync it with iTunes, make sure everything is good, and then prepare the old ones (My dad's 3G, and my 3GS, but I think the 3G can downgrade fine without SHSHs) for the sale.

    You could go into settings then tap reset everything and wipe data then JB+Un it.

    this. but if your already jailbroken on it then DONT reset it. it will force you to restore anyway. if you do it then it will have an infinite boot loop.
