So, the morning after the night before.

After all of the excitement of the Steve Jobs keynote yesterday and the unveiling of iPhone 4, it’s now time to discuss hard, cold facts: dates, pricing, and tariffs.

As you may already be aware, Apple’s next generation smartphone will be released in the UK on June 24th. Pre-orders will be taken from 15th June.

Both O2 and Vodafone have already posted a pre-registration page for customers frothing for some fresh 32GB Apple goodness.

The original, exclusive carrier of the iPhone in the UK, O2, have also announced via Twitter that existing customers will get a ‘limited time, special upgrade offer’. As always, more details to follow.

For their part, Orange has done the sensible thing and released a statement to TechRadar confirming that it will indeed stock the fourth iteration of the iPhone.

But what about Tesco Mobile? No official word yet.
