Long overdue, Skype has finally made its way to the Android platform, but only if you are running Android 2.1 or 2.2. Older handsets are presumed to lack the processing power needed for a decent service.But if you have the necessary version of the operating system, head over to the Android Market now, you can download and start saving yourself some cash. Well, that's the theory anyway. Skype to Skype calling is the headline feature, with free calls over Wi-Fi and 3G. However, if you have a call allowance you don't make great in-roads into, it might not be much of a saving, especially with the added pressure on your data allowance.In that case, there's always the added bonus of IM chat with multiple buddies at a time and you can update your profile on the go, should you need to. You can also sync friends on Skype with contacts on the phone, which means you can call or 'message' directly from a person's contact page.If that appeals, grab it now. The app is free, so there's nothing to lose, except maybe a couple of minutes of your working day downloading it.
