Hey all, I have an iPhone 3GS running 4.1, that i have jailbroken (with redsn0w), and unlocked to the baseband 06.15.00 (i had no choice to use the 06.15.00 baseband due to me having T-Mobile and my original baseband couldn't be unlocked). What steps do i have to take to upgrade from 4.1 to 4.3? Can i upgrade to 4.3 with my current 06.15.00 baseband and keep my jailbreak? If so, how can i restore all of my Cydia things (apps, tweaks, etc) when i upgrade? If you have any advice on how to do this, i would greatly appreciate it. I'm pretty new to the whole jailbreaking/unlocking world. Thank you guys very much!
