Unfortunately HTC didn't offer an official bootloader unlocking solution (just yet) for the AT&T One X but this didn't stop the community and its fine developers from working on a solution (and they have found one)!
The community not satisfied with the way HTC implemented multi-tasking in Sense 4.0 and the Taiwanese manufacturer issued a statement saying "multitasking is operating normally according to our custom memory management specifications which balance core ICS features with a consistent HTC Sense experience".
The HTC One X for AT&T and the upcoming HTC EVO 4G LTE for Sprint -- which should hit the shelves this Friday, May 18 -- appear to be delayed by U.S. Customs, according to an official statement released by the Taiwanese manufacturer. The reason behind the delay, according to the wording, is "standard U.S. Customs review of shipments that is required after an ITC exclusion order".
The phone we used to know by the codename Golf -- which made an appearance recently -- was rumored to end up on shelves as either the HTC Wildfire C or the HTC Desire C. The Taiwanese phone maker made the device official and the HTC Desire C is their newest Android smartphone with Beats Audio integration. It is marketed by HTC as an accessible device but with a premium design.
