While it may not be the holy grail, it's definitely one of the most prized treasures of thus-far undelivered iPhone apps: Skype. Well, GigaOM says maybe not for much longer:

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.

Dieter will be live and in-person at CTIA, eyes peeled and iPhone at the ready, just in case. Meanwhile, we have to wonder what the carrier reaction will be. We know consumers want it, right?
