I am currently running 4.01 on my 3G. My 4 is due to arrive on Wednesday. I want to unlock my 3G after my 4 arrives so my wife can use the 3G on TMobile.

Can someone look at my steps below and let me know if I am missing anything or doing anything wrong to get the 3G jailbroken and unlocked so she can use on TMobile.

1. Before activating my iPhone 4, reset the 3G in settings > general> reset> Erase all content and settings
2. Since my original AT&T sim card is still in the phone and still active I will be able to accress Safari and go to jailbreakme.
3. After completing that go to cydia and download ultrasn0w for the unlock.
4. Remove my AT&T sim card and install the TMobile sim card.
5. Activate the iPhone 4 using iTunes and restore from last backup I made.

Are my steps correct? Is that all I need to do to make this work? Thanks
