iPhone 5- or is it just a 4S?

Convincing evidence released yesterday suggests that it will not be an iPhone 5 but an iPhone 4S which is released at 6pm GMT. iTunes Beta devices bar lists a 4S, but not an iPhone 5. However, Apple have been known for decided craftiness, and they'll keep us guessing right up until the conference. Whatever the outcome, we'll be doing a live blog, so join us at 6pm!
