Hi All, Need to unlock a 6230b for my Dad who is traveling overseas. Can anyone help- tried 3 times and afraid I am going to brick it. Provider: AT&T (formally cingular) in USA IMEI #: 355032000470462 Any help would be appreciated. Also confirmation from anyone if this is 3G. I have looked around and believe it is- just want to make sure he can use it too on the new ATT network. Thanks in advance
