AT&T call charges are sky high (especially International ones) which makes VOIP a necessity for iPhone, yet Apple has yet to allow a proper one. A good one like Skype could rock the AppStore - and according to GigaOM, it's not far way!
Though Skype has been available via third party apps like Nimbuzz and Fring for quite some time, none of the apps have proved remarkable as of yet, which makes a standalone Skype app for iPhone a brilliant idea.
A tipster — a very reliable one — tells me that Skype is almost ready to launch that iPhone version, perhaps as soon as next week. CTIA Wireless, a large mobile industry trade event, kicks off in Las Vegas next Wednesday, so perhaps the announcement will be made there. I am working on getting more details, as well as screenshots of the service.
