The Three Network in Australia offers Skype as an offering on its plans. This means that you can call a Skype contact directly from your phone and Skype contacts can call you to your phone when you are online with 3’s Australian 3G network . The allowance is very generous as well with 4000 minutes a month allowed. The only problem is that there is a bug. Skype allows the underscore character “_” in user names, Three’s E71 does not. Three’s other offered mobile applications such as Yahoo 7, MSN etc all allow for the “_” character. Just their Skype application does not.
