Updating unlocked and jailbroken iPhone 3GS
I have a 3GS that I purchased from ebay about a year. It is unlocked and jailbroken on version 4.0 and I use T-Mobile.
Is there a way to update it to the latest version without messing up the unlock?
I tried this once before on accident and it messed up the unlock and could not unlock it again. Will this happen again?
And if not, how can I go about updating it?
Welcome to PinStack, leebee!
I'm sure there's a way to do this. I'll see what I can dig up for you.
