Holland's largest carrier KPN mentions iPhone 5 on their website saying: "Everybody is eager to know when the iPhone 5 will be released even we still don't know anything" Seems that even they are fed up waiting. But if a major carrier like them mentions this on their site, it can't take that long anymore for the final release.
