HTC One X+

Details and images of HTC's One X+ smartphone have been leaked by mobile network O2.

The rumoured handset has appeared in promotional material posted by GSMarena. The phone looks almost identical to the HTC One X but with a few changes in specification. Visit Group test: what's the best smartphone?

According to the brochure, the HTC One X+ is 'coming soon' complete with 64GB of internal storage and Android 4.1 Jelly Bean. It will also have a 1.7GHz quad-core processor, 8Mp rear camera and 25GB of free Dropbox cloud storage.

O2 recently announced that it would sell an upcoming HTC smartphone without a charger so it's possible that the One X+ is that handset.

The HTC One X+ will be priced at £479 on pay as you go but no details on monthly contract prices or a release date. However, the known price is a fair amount less than the equivalent iPhone 5 model.

Pocket-Lint received an exclusive image of handset showing the front and back. You're keen eyed if you spot the difference between it and the original One X. The only change we can see is the different Beats Audio logo.
