I have posted this on here but other users feel they can just tack their question onto mine...frustrating. I have an iPhone 4 with 4.0 installed. I jailbroke it using that jailbreakme.com site. I have not unlocked it nor do I ever plan to. I want to upgrade to 4.1 in iTunes. Can I just upgrade without any issues and keep the jailbreak? Or do I need to do something special to have 4.1 and a jailbroken phone? Is it even possible to have a jailbroken phone and 4.1? Thank you!
