Huh...what's wrong with 4.3.3?...I'm on 3GS rocking 4.2.1 jb w gp...buttery smooth! 4.2.1 best on 3GS I always say....

If u dont have shsh blobs for it u can't go back though....

I have seen 4.3.5 on 3GS in Att store, looked smooth enough but no untethered jb for that...or unlock I don't think...I won't go up cuz I had bad experience on previous 3GS on update from 4.2.1 to 4.3! 4.3 ruined it for me. Swapped phone for unrelated issue and this one came with 4.2.1 still on it! I don't think I'll ever update.

nothing wrong with 4.3.3 just wanted to restore the phone i have found out that i can only restore to 4.1 so should downgrade the phone o 4.1

use ifaith to dump your 4.3.3 shsh blob first before you do any downgrade just in case you want to restore back.

i have saved that with tiny umbrella whats ur opinion should downgrade to 4.1

if you want to downgrade to 4.1 :
With your 4.1 blob saVed in TU, start TSS server ,

Method one
> Put iphone into dfu mode , restore to stock 4.1 and use exit recovery to kick error 1015

Method two
> Put iphone into pwned dfu and restore to custom firmware of 4.1

I restored it with custom firmware bcoz of the baseband is there a way to downgrade the baseband or to permanently unlock the iphone from the carrier


my iphone Baseband is 06.15.00
