HTC One X is expected to receive the update to Android 4.1 (Jelly Bean) in October. The MoDaCo reports HTC's plans for rolling out the Jelly Bean update for One X.

"HTC will be starting the rollout in October for generic devices with rollout to all devices (including operator branded units) set for completion before Christmas (subject to operator / Google approvals etc of course)," claims MoDaCo.

The unannounced One X+ is expected to be shipped with Jelly Bean "out of the box", while the One XL, the first 4G smartphone to be made available on the Everything Everywhere (EE) network, is expected to pack Google's latest operating system.

There is no word about Jelly Bean update for the One S. However, the Taiwanese handset maker confirmed rollout of the update to three of its smartphones - One X, One S and One XL - in July, while it has remained tight-lipped in regard to the timing.

SlashGear has received the official statement from HTC saying: "We know HTC fans are excited to get their hands on Google's latest version of Android. At this point in time, we can confirm that we have plans to upgrade out HTC One X, HTC One XL and HTC One S to Jelly Bean."

The exact date has not yet been confirmed by the company. "Please stay tuned for more updates regarding device upgrades, timing and other details about HTC and Jelly Bean."
