The AT&T version of the very impressive HTC One X will be landing in US tomorrow on May 6. Unfortunately, even before customers can get their hands on the phone, there is a disappointing bit of news waiting for them. When The Verge reached out to HTC regarding the bootloader on the One X, which, as noticed by MoDaCo, is locked, the company responded by saying that due to some restrictions, the bootloader on the One X will not be unlockable.
As you may know, an unlocked bootloader is necessary for anyone wishing to experiment with custom ROMs on their Android devices.
