UPDATE (6:50 AM EST June 8): The $99 offer is already gone, which can only mean it was highly successful. The new package deal now costs $298.99 after a $100 online discount and $400 instant savings with contract, compared to the full package price of $798.99.

The HTC One is one of the hottest, most powerful high-end smartphones currently available on the market and AT&T now sweetens the deal with an attractive freebie.

Although it faced some initial supply woes and tough competition from archrival Samsung Galaxy S4, the HTC One still sold more than five million units worldwide in just 30 days since launch and is one of the most popular Android smartphones around. It's currently available on all major U.S. carriers except for Verizon, but Big Red will join the party soon enough.

AT&T occasionally offers package deals to entice buyers and its current deal is particularly attractive: just $99 for the 32GB HTC One and a Beats Audio Pill Bluetooth speaker. As one would expect, the offer goes with a two-year contract with the carrier and the $99 price tag is for the package only.

AT&T customers who want to buy the HTC One by itself, not part of this package, will have to pay $199.99 on a two-year contract. In other words, one can pay $99.99 to get the HTC One and the Beats Audio Pill Bluetooth speaker bundle, or pay $100 more to get only the handset. Considering that the Beats Pill costs $199.99 by itself from the carrier, this package deal will actually save customers a total of $300.

The HTC One boasts top-end specs and features, including a 4.7-inch Super LCD3 1080p display , a 1.7GHz quad-core Snapdragon 600 processor, a 4-megapixel "Ultrapixel" camera, NFC, LTE, a 2,300 mAh battery and other neat features. HTC's new flagship smartphone runs on Android 4.1.2 Jelly Bean.

The Beats Audio Pill, meanwhile, is part of a new line of mobile-centric Bluetooth speakers that come with integrated batteries. The Beats Pill comes with both line-in for non-Bluetooth devices and line-out for connecting to larger stereos, as well as an internal microphone allowing the gadget to serve as an external speakerphone. The Pill also has an integrated NFC reader, which allows it to pair with compatible smartphones such as the HTC One.

The HTC one and the Beats Pill definitely make a good team for blasting music on the go and AT&T knows a thing or two about marketing. If you're in the market for a brand new HTC One, will you consider becoming an AT&T customer to take advantage of this package?
