HTC One X and its Quad-core Tegra 3 visit the FCC with support for AT&T's HSPA+ network12
equipped with radios tuned to AT&T's HSPA+ bands. What this means, if you are willing to pay the retail price of an unlocked version of the phone as an import, you will be able to use AT&T's HSPA+ network and have the Quad-core power that you wanted. Besides the extra cost over a subsidized handset, you need to understand that you won't be riding the carrier's LTE pipeline but then again, not too many will be. All you will need is your AT&T SIM card to make the connection. And we should see unlocked versions of the phone available from Amazon.co.uk and other European retailers next month when the phone is expected to launch.
Now that we have brightened up your day, we hate to remind you that it is Monday!
