Skype was probably one of the most anticipated and much wanted applications for iPhone. While some of the all-in-one instant messengers like Nimbuzz do provide Skype connectivity, I always prefer an official application.
I installed Skype on my iPhone immediately it became available on the App Store. Unfortunately, the application crashes and shutsdown frequently. No, practically it's useless. I'm not sure whether it is my iPhone to blame or there are some problems with the application. Anyhow, it's really great to see Skype coming to iPhone and hopefully the developers will quickly fix whatever problems or bugs may be in the current release.
Download Skype for iPhone now! It's free of course.
