Sure, the Samsung Vibrant’s a T-Mobile device and the Samsung Captivate belongs to AT&T, but there’s now not any reason that you could’t swap them around — all you want is a straightforward script and a USB cable to absolutely unlock your phone. Dagentooboy of XDA-Developers discovered that Galaxy S unlock codes aren’t kept in a secure remote server, but merely stored in a .BAK file on the device itself, which you find with a hex editor and key right in when inserting a new SIM card of your choice. We tested it out on both Vibrant and Captivate and were up and running in under five minutes whenever, and wonder of wonders, the Vibrant gave us a 3G data connection (with 2Mbps down) using an AT&T SIM. Sadly, we will be able to’t say the inverse for the Captivate, which pulled down standard EDGE speeds on T-Mobile, but it truly is already excess of the hacking community will have hoped for. The simplest part? None of this requires you to actually root the phone, and in case you’re worried about warranty you may re-lock the handset with the very same code.
