Rumors of HTC's flagship model's One X's successor, the One X+, have been floating around for a few months. The newest addition to the rumor mill is a picture of the One X+ with a T-Mobile logo.

A recent Twitter post, by a user who goes by the handle "@evleaks," says "HTC One X+ for T-Mobile USA" and includes the alleged image of HTC One X+ with T-Mobile's logo.

The Taiwanese smartphone maker HTC has not officially announced the One X+, but details of its specifications have already been leaked twice.

Earlier this month, in a Twitter feed, an XDA developer revealed the specifications of an HTC device purportedly named the One X+. If speculations are to be believed then a Tegra 3+ AP37 1.6GHz quad-core processor/1.7GHz single-core will power the device. The current leaked image does not reveal much apart from a black device with T-Mobile's logo.

Previous leaks have indicated that the handset will measure 5.28 x 2.75 x 0.36 inch (134.36mm x 69.9mm x 9.3mm) and weighs 4.55 ounces. The One X+ is expected to pack in HTC Sense 4.5 running on top of the latest Android 4.1 Jelly Bean. Similar to its predecessor, the HTX One X, the One X+ will likely have 16/32GB of on-board storage and 1GB of RAM. An 1800mAh battery will boost the smartphone.

Camera features of the device have not been revealed by the rumors; however, like the HTC One X smartphone, users can probably expect at least an 8-megapixel rear-facing camera with autofocus and LED flash. Like its predecessor, the device may sport a 1.3 megapixels or a better front-facing camera.

To keep abreast with current technology, users may expect Wi Fi, Bluetooth, and Near Field Communication (NFC) capabilities on the device.

The smartphone market is flooded with a bevy of handsets from leading brands like Samsung, Apple, Nokia, and LG, making it challenging for many consumers to pick a device. Time will tell which device leads in the free-for-all battle for supremacy.
