already jailbroek iphone 3g 2.0.1 want uprgrade 2.2.1
Hi all, This is my first post here, I hope it will be more helpfull than at other forums where no one has responded . I've done my research, but all thats out there is tutorials on how to upgrade a locked iphone, not an already jailbroken one.
I have an already jailbroken iphone 3g (1st gen) that I pwned using winpwn. It is currently running fw 2.0.1 and I want to update to 2.2.1 while also preserving the baseband. Currently i'm using a gevey turbosim with a t-moble sim but it sucks (doesn't recieve calls often, even though it says i have full signal) and i would like to use yellowsn0w. I have a pc with both a vista partition and iatkos 4a partition (so i can run leopard on my comp, not emulation..real thing).
1.) First off do i need to upgrade to 2.2 before going to 2.2.1? If so how should i go about this if my phone is already jailbroken (do i need to unjailbreak first?).
2.) Also I left my original at&t sim at school, do i need this in the phone during these processes, or can i take out my t-mobile sim and have no sim in there, or can i leave my t-mobile sim in there? (I asume taking out the turbo sim is probably a good idea). I've seen elsewhere people saying just use itunes to update to 2.2 if your phone is already jailbroken, but at this point I think itunes wants to update me to 2.2.1 and that would be bad and loose the baseband.
3.) Now when i want to update to 2.2.1 using pwnagetool on my iatkos (leopard), can it already be jailbroken, or do i need to reset it (kinduv a repeat question)? I know it prompts you and asks if it has already been jailbroken, but does it matter that i used winpwn and not pwnage tool.
P.S: the iatkos 4a (leopard) is below 10.5.6 meaning it should be able to see my iphone in DFU mode. And if anyone has tried to use pwnagetool on iatkos i would be curious to hear if it worked, thanks so much if you can help
