Best Buy is now accepting pre-orders for Nokia’s flagship Lumia 920 as well as the HTC 8X. The AT&T exclusive 920 will retail for just $149 while HTC’s handset can be yours for $99. Pricing for both includes the typical two-year service agreement subsidized by service providers. If you’d like either phone without a contract, prepare to shell out $600.

Nokia’s handset is expected to be a serious contender in the smartphone race. With a price point of $150, it also significantly undercuts other high-end handsets like Apple’s $199 iPhone 5 and Samsung’s upcoming Galaxy Note II which will retail for $299 with a two-year contract.

If you aren’t familiar, the HTC 8X ships with a 4.3-inch Super LCD 2 display sporting a resolution of 720 x 1,280 with a pixel density of 342 that’s coated in Gorilla Glass, a Qualcomm S4 1.5GHz dual-core processor, 1GB of RAM, 16GB of internal storage and an 8-megapixel f/2.0 rear camera.

Features and specifications on Nokia’s Lumia 920 have been well-documented so I won’t rehash those. If you need a quick refresher, feel free to check out our recent comparison between the Lumia 920 and several other high-end handsets.

The Lumia 920 will be available in black, cyan, red, white and yellow while the HTC 8X is only offered in purple. Best Buy’s website doesn’t list a shipping date but instead notes that phones will ship when they are available. We’ll likely have to wait until October 29 for Microsoft’s Windows Phone 8 event to gather more details on a release date.
