HTC and Telstra have already had a pretty successful 4G mobile network relationship, what with the HTC Velocity and recently announced HTC Titan. Now, Telstra is grabbing the rights to the HTC One XL, the 4G version of the HTC One.

Almost identically spec’d to HTC’s One X, the XL isn’t extra large, but does feature an extra speedy mobile downlink, taking advantage of the LTE connection on offer at Telstra, offering up to 40Mbps downloads in metropolitan areas.

Outside of the high speeds, you’ll find a 4.7 inch screen with 720p resolution, 8 megapixel rear camera with LED flash, 32GB storage, Near-Field Communication technology (NFC), Bluetooth 4.0 with A2DP, 129 gram weight, and a thickness of just under 9mm (8.9mm).

Unlike the One X, you won’t find the Nvidia Tegra 3 quad-core processor powering this beast, with HTC choosing to go with a dual-core 1.5GHz chip instead, but we don’t anticipate that slowing down the HTC One XL that much, especially with the latest Android operating system – 4.0, “Ice Cream Sandwich” – existing in this handset out of the box.

You can find the HTC One XL available from June 1 for both consumers and business customers, with the first 300 orders receiving a pair of Beats Solo headphones.
