Hi, I am new on the site, new with iPhones and could use some help. I have purchased the iPhone 4s and it has the IOS 5.1 on it. I do a lot of international travel and need my ATT locked phone unlocked. I have been trying to find a solution for this online and so far seems that there isn't a way to unlock the IOS 5.1, at least as of yet. Then I found this website www.unlockiphonetool.com and I emailed them and got this as a response: Yes, our tool will be able to permanently factory unlock and untethered jailbreak your iPhone 4S on iOS 5.1 with baseband 2.0.10, so it can be used on any network worldwide. After the purchase, you will require to submit your IMEI code and we will take care of everything else. This is the full lifetime unlock solution - your phone's identification number IMEI is registered as unlocked in Apple's database. Unlock process takes 10-20 days, and jailbreak is instant. Does anyone know if the iPhone 4s with IOS 5.1 can be unlocked or is this website a scam? Does anyone have any experience with this seller? Thank you so much for your help!!!!
