It looks like the eagerly awaited iPhone SDK kit has been delayed. This is a major blow to this iPhone users waiting for a legitimate way to add software functionality to their phones.

Yesterday US publication Business Week claimed that good internal Apple sources had relayed to them that the SDK kit would be put back about 1-3 weeks. This realy isn't that surprising as the Apple TV Take 2 release also slipped by about the same length of time.

It should be pointed out that the February release date that has been promoted around the web has never actually been formally recognized by Apple Inc, so the true release date could be further off than the February special event anyways.
