Today I received an email from Skype which promoted the built-in Skype on mobile phones. This allows users who have Skype on their mobiles to talk with each other without using minutes on their wireless plan. Skype is available in US on Verizon Wireless phones (BlackBerry) , Android phones, iPhone (via an app) and on other handsets as well. Of course, you can also use Skype on your mobile phone to call other phone numbers directly and not incur wireless minutes. The price can be high though. Calls to Pakistan are over $0.156 per minute.
