Yes you can - upto £1000 for an iPhone 4 32GB unlocked before the 24th June. Still retailing for above the £600 list price.

But why - I have switched from the N97 to N900 and now the iPhone 4 and I would say that this is the cats whiskers - there is no reception problem for me (and I dont live in a built up area). My signal is no worse than the N900 or the wifes 5800XM.

The N900 is a good Tablet/developers phone. It has its pluses and minuses. I like it. Shame it wasn't supported properly.

The iPhone 4 is a good toy/gadget/phone. It has pluses and minuses. The main minus is you MUST hold it correctly or do as I have and buy the bumper. The bumper to me is dual role - 1) the reception is fixed. 2) The rubber edge stops the screen/back getting damaged when the phone is put down and due to the slippery glass on the front and back of the phone it stops the phone sliding off a slight gradient (happened to me a few times already).

Both N900 and iPhone make calls.

The N97 was absolute RANK but you didnt hear much about that yet all the UK carriers stopped selling it with months of its launch due to the complaints and failures.

Apple have said they will give us all a full refund if not satisfied within 30 days. Lordy - if only Nokia had done that with the N97. Credit to Applecare here. I have looked around the shops today. I cant see anything I would rather have than the iPhone 4 and I have had Nokia's for years. Maybe the N9 if it was out and Meego was mature. Maybe not.

Lets watch the story unfold!

Lastly - the biggest thing I miss from the N900 - The keyboard, but I need to get used to the virtual keyboard.
