In addition to the LG Viper due out this spring, Sprint plans to add Google Wallet to nine other phones within the year.

The wireless payment service that lets you pay for items with your phone through an NFC chip, is currently available on only two phones: the Nexus S and Galaxy Nexus.

According to Fierce Mobile Content, Vice President of Google Wallet and Payments Osama Bedier said that Google will continue talking to other operators, manufacturers, and financial institutions to expand the Wallet's reach.

CNET's own Marguerite Reardon remains skeptical of the money service, given that it's still rarely featured despite being out since September 2011.

Along with security and privacy flaws, an upcoming rival service called Isis threatens Google Wallet's breadth. But for those who want Google Wallet to succeed, the news that Sprint plans to bolster the service with these yet-to-be-known phones should alleviate some concerns.

In addition to Google Wallet, the LG Viper will have a 4-inch Nova touch-screen display, a 1.2GHz dual-core CPU, a 5-megapixel rear camera, and a 1,700mAh battery. It will run on Android 2.3 Gingerbread, but will be upgradable to Ice Cream Sandwich later.
