Skype mobile lets users make free calls to landlines and mobile phones internationally, as well as send IMS to other Skype users. Skype-to-Skype calls are free and don't count towards Verizon Wireless minutes.
Calls o other mobile or landline numbers in the U.S. do count toward Verizon's minutes. Calls to international mobile or landline numbers can be paid for using Skype Credit or other subscriptions.
Skype mobile for these devices can be found at the Verizon Media Store. Users can also text SKYPE to 2255 to get a download link. The service is also available for Android and Blackberry (on some devices) on Verizon.
Skype recently filed for its IPO and launched "Click to Call" ads for businesses to place around the web. In addition, the company has picked up Yahoo's VP of Engineering and expanded its operations in Silicon Valley, while facing growing competition from companies like Google.
