It’s no surprise that the HTC One X is currently one of the hottest Smartphones. However, HTC One X bought through AT&T are locked down devices, but no worries as talented developers from XDA forums have cracked the HTC One X bootloader to unlock the phone.
Apparently an XDA member who goes by the name grankin01 was able to “unofficially” unlock the device by tricking it into thinking that it is the One XL from Rogers Canada. A simple swap of the hex value now disguises the One X as a Rogers One XL and will now be granted full access to the unlock tool. The process is rather lengthy but is actually quite simple in theory so if you are familiar with adb and a hex editor you may want to give it a go. You must be rooted and if you have already manually upgraded your device to the recent OTA leak this will not work for you.
HTC One X owners can head over to this thread on the XDA-Developers forum to learn more on the matter.
