I wish they would release some information about what is happening tomorrow. Are they going to try and make us pre-order a non existent contract and hope we'll pay. I really want to know how much the phones are going to cost on contract, hopefully not ridiculous prices though others I'll stick another year with my first gen.
You can't pre-order contract phones from Apple in the UK - so it is unlikely you will be able to pre-order tomorrow unless the networks decide to offer pre-orders through their own websites or somewhere like Carphone Warehouse or Phones 4 U start pre-orders.
Last year I don't think any of the networks offered pre-orders, other than Vodafone.
