I have a 1.0.2 iphone that is using AT&T as my carrier. I have preformed the jailbreak on my phone and only use the apptapp installer for all my 3rd party apps. That is all Ive done to my phone.

I want to upgrade to the new firmware, then jailbreak the phone again so I can use apptapp installer.

1. Is it really as simple as doing a system restore, update the firmware, and jailbreak by using iNdependence? (where is the guide for this?)

2. Or is there something else I need to do?

3. Do all the apps from apptapp still work the same?

I find everything confusing, because of the guides that say I should revirginize my phone before I do anything. I have not been keeping up with all the new stuff that is going on. So if anyone could help me, I will buy you a cookie. thanks.
