Owners of the unlocked HTC One have already received the update to Android 4.3 Jelly Bean, but now it's time for the smartphone's US carrier variants to get the goods. HTC USA took to Twitter today to announce that the 4.3 rollout is starting for Sprint customers now, with AT&T and T-Mobile set to get the update later in mid-October and Verizon by the end of the month. The latest version of Jelly Bean, for those who need a refresher, brings improved low-light camera performance, a battery charging percentage indicator and the usual bug fixes.
