Unlock iPhone 3GS on iOS 5.0.1 using 5.16.05

[AJH1993]

Got a new iPhone 3GS from Apple after I bought a used one on ebay and bricked it, friendly seller still had Apple care on it. Don't need it any more so I want to re-sell it as new, but want to get a little more money for it by unlocking it.

It's running iOS 5.0.1 and is running an unsupported unlock baseband; 5.16.05 and I have the option to upgrade to the iPad baseband which IS supported. Problem is I unlocked the other iPhone 3GS with the iPad baseband, lent it to someone in Canada and he said it didn't work. I have no T-Mobile SIM card to test it on, only AT&T. Help?

Your only option if you want to unlock it is to put an Ipad baseband on it. However, you need to look at serial on your phone to make sure it is made before 2011, week 35. Otherwise, you might become an ipod touch if you do this.
