Does HBOOT 2.15 actually exist for an AT&T version of the One X (or One XL if you must) for this to be a problem? I keep seeing the Telstra people with HBOOT 2.15 but where is this coming from? I'm asssuming HTC and AT&T have no plans to give us any future upgrades, but I have already gone to Sense 5 with MagioROM and love it. Always looking to be on the latest firmware however. I just get confused when I keep seeing people mention something I don't know to be in existence..
Yes it exists, whether it's an at&t, Telstra, Rogers etc phone it is compatible, they're all the same phone. You can find it in the OP of Turge's stock ROM thread. It comes with any of the official updates that were released a week ago.
