12-27-2012, 12:58 PM #1Jailbroken iPhone 3Gs > vers. 4.1 to 5.0.1 (help)
I'm currently using an iPhone 3Gs (model MB717LL/A, serial # QR11505D3NR) jailbroken on 4.1 firmware, and I'm looking to upgrade it to a jailbroken 5.0.1. I have the necessary SHSH blob, but I'm not really sure what to do with it. I've jailbroken devices before, ipod touch specifically, but I'm unfamiliar with the technicalities of preserving baseband and stuff like that with iPhones. I know that this phone is currently unlocked, and I'm using a carrier that would otherwise not work. I suppose this means that whatever I do, I'm going to want to preserve the baseband to preserve the unlock.
I was hoping to have some specific guidance for my case cause I don't want to mess up the unlock and then have a phone that I can't use without a rogers sim card or something (I'm with Fido at the moment).
Thanks, I appreciate any help.

Any reason u want to go to 5.0.1 and not 5.1.1? This is my tutorial from another thread..
This is what I do on my 3GS... I think this works for a 4... This is a slightly modified version of my previous tutorial on 3GS for folks that didn't unlock...this should work for unlocking..at end of course u have to JB and install ultrasn0w as before...I've not done this myself all the way through as I don't unlock, so proceed at own risk. Would like to know I it works though...
