CNet is reporting that a free Skype client will finally be landing on the iPhone this week. Unfortunately some are saying that it seems many of the "critical" pieces of functionality are still missing. While the Skype engineers claim their native client will offer better audio quality (because there is no need to route through another server and transcode audio) they are still missing text messaging, file transfers, and integrated voice mail. Since the iPhone does not allow for multiple programs running concurrently, many are expecting existing multi-function apps like Fring and NimBuzz to continue their reign at the top.
