Google yesterday unveiled the latest flagship smartphone for Android, the Nexus 5. The device can boast a number of impressive specs but the most notable is that it is the first smartphone to come stock with the latest version of the Android operating system. Android 4.4 KitKat has officially begun and now, HTC and Google's own Motorola are going to begin rolling the technology out across their respective cell brands.

According to PCMag, Motorola users can check their phone's compatibility using the manufacturer's chart, located HERE. If you simply search for your carrier and model you will be able to determine if you'll be able to receive the upgrade.

Motorola's phones that are eligible for the upgrade include the Moto X as well as the new Droid phones like the Droid Ultra, Droid Maxx and Droid Mini. Meanwhile, the Razr HD and Razr Maxx HD are not eligible for the upgrade.

HTC has also announced its Android 4.4 plans. According to reports from Engadget, Google Play editions of the HTC One should see the update within 15 days. The developer has unlocked versions of the phone available within 30 days and everyone else should expect it within 90 days. HTC phones that run KitKat will still implement the manufacturer's custom Sense UI 5.5.

The phone is coming to Sprint and T-Mobile as well as several other retailers later on in November.
