HTC's new One X phone is the most sophisticated and technologically powerful phone by HTC yet (and HTC has put out some pretty monstrous phones). Because of that, Best Buy thinks customers will be all over it and has decided to already begin taking pre-orders for the device. You'll need to specifically ask a Best Buy employee for the pre-order, as it isn't advertised in the store.
The One X will be powered by Android 4.0 Ice Cream Sandwich, wrapped in HTC's new Sense 4.0 interface, and it powered by a quad-core processor. It comes with a 4.7-inch display and is compatible with AT&T's super fast 4G LTE network. In other words, it's the kind of phone that you'd want to show off to your friends. There is no launch date or price to confirm at this time, though.
That isn't stopping Best Buy from taking your money, though. If you place a $50 deposit you're guaranteed to get one when it launches, whenever that may happen to be. Of course, you can rescind your reservation at any time and get your money back. Just like most pre-orders, this is all about showing how excited you are for the new phone.
