Hi all, I have an iPhone 3GS that's been upgraded to iOS 5. I want to jailbreak it to work on tmobile. Its for my teenage daughter, so I want to have a non tethered solution. Questions I have: 1) Should I downgrade it to 4.x before jailbreaking it? if yes, what version? 2) Is Redsn0w the way to go? Again, this needs to be a non tethered solution. any guidance would be appreciated as I am a JB n00b! thanks!
