[TUT]Upgrade iPhone 4 to 4.2.1 {PRESERVING BASEBAND+HACKTIVATION+JAILBREAK}

For LEGIT certs, you'd need an official AT&T sim card. Use SAM to deactivate, and reactivate with the official SIM. You get your own unique certs.

I am cursed, no service and 1 bar network is back, i have to do like a reset network settings 4-5 times at least to get my network, I am 100% sure the issue is with ultrasn0w, is there a possible fix for this?
My phone just dies without network and i don't even realize, the battery drains in less than 8 hours, what could solve these issues?

Any help will be greatly appreciated.

Hey I don't see any option called "deactivate iphone" under SAM, where could I find that option? Should I use redsn0w ? But you said to skip that step?

Please guide me on this one!

Thanks
