Skype is a voice over ip client for the pc that is now available for the iPhone and iPod Touch. Skype has easily earned it's name in the online communications business and remains one of the most recognized companies in the business. With the popularity of Apple's devices, it only made sense to make the leap into the mobile world. Skype for the iPhone just like it's computer counterpart it offers a multitude of features and is missing just as many. Starting the app up, the user is offered a chance to sign in using their Skype account or create a new one right in the app. After signing in, you'll be taken to the main contacts page. From there users can make a call or start a chat with anyone on the list. What's so exciting about Skype for the iPhone is that Skype's rates for international calls are ridiculously cheaper than AT&T or other providers and it's cheaper to call from Skype than to pay for extra minutes on a plan. This enables users to have a backup on their phone just in case they run out of minutes or head out of the country. Skype only works on WiFi currently although there are rumors it works on 3G in the iPhone 3.0 beta. The interface is fast and responsive and the calls are perfectly clear (as we should expect from Skype). It's is missing video chat, SMS, good conference calling and a few more features. But for a free app that handles VoIP well, it a definitely worth checking out. With future releases from Apple, Skype is sure to add more features.
