The Android 4.4 KitKat update for the HTC One continues, with T-Mobile rolling out the new system on its HTC One model.

Several users began reporting the new system hitting the HTC One on Friday, not long after HTC Executive Product Manager, Mohammed Versi, announced that both the T-Mobile and AT&T HTC One models had received technical approval. The ever-transparent HTC also held an  “Ask Me Almost Anything” session on Reddit last week where executives mentioned that updates for the T-Mobile and AT&T HTC One were not far away. In addition, they announced that HTC would be providing software support for flagship devices up to two years after their release. The Taiwanese manufacturer later detailed that its support plan is a feature of its HTC  Advantage  extended warranty program, now in place for newly purchased HTC One, HTC One Max and HTC One Mini models.

The T-Mobile HTC One update follows a delay in the Android 4.4 rollout, which HTC announced at the end of January. The manufacturer was aiming to have U.S. carrier models updated to Android 4.4 by late January, but the certifications that U.S. network models require before pushing out system updates delayed that timeline. Since then, the Sprint and Verizon HTC One models have updated to Android 4.4 KitKat, as have several Canadian HTC One Models.

The Android 4.4.2 build version 4.19.531.10 for T-Mobile HTC One users includes the HTC Sense 5.5 UI as well as various security enhancements, the cloud print service and new Bluetooth profiles. The update is available over the air, but users can also check to see if Android 4.4 is available for their handsets, manually accessing: settings > about phone > software updates.

The AT&T HTC One has not yet updated to Android 4.4. Versi says the model is expected to update on Monday.
