Hello all, I have a 3gs. Version 4.1 with firmware 06.15.00, unlocked or jailbroken (something that requires Cydia) I want to upgrade to iOS 5, but I dont really care for my jailbreak or if it is unlocked. If fact, I would prefer if it were not unlocked or jailbroken. I only did this because I lived in another country for a few months. Can I still do this on my own (without resulting into my phone becoming a brick)? Can i just press upgrade right away, or would i need to restore it first and then upgrade it? Does it make a difference? Or would I have to go to a shop somewhere and get it upgraded? The last time I upgraded my phone, some error came up and it got stuck on recovery mode. I had to get fixed in a shop, where the guys jailbreaked or unlocked it again. Thanks for your help. Let me know if you need any other info that I can help you help me.
