Research In Motion's answer to the iPhone 3GS, for now being called Storm 2, is expected to be released by Verizon in October, along with Motorola's Android-powered handset code-named Sholes.

A leaked Verizon Wireless document outlining upcoming smartphones hit the blogosphere this week, and according to reports, highlights mobile devices that will be on sale by the holidays.

In addition to the BlackBerry Storm 2, Verizon is on tap this fall to sell an updated version of the Curve 8520 that includes Wi-Fi.

Motorola and Verizon are also slated to begin offering the Sholes handset, which could be the first Android-powered smartphone for the wireless carrier. It will also mark Motorola's push in the fourth-quarter to reinvent itself as a viable contender in the lucrative smartphone market with a new line up of Android phones.

There is widespread speculation that Motorola's Sholes will run on the updated version of the Google-backed mobile OS, version 2.0, or eclair, and will cost $199. It's also expected to boast a 5-megapixel camera and 3.7-inch touchscreen.
