O2 Offering iPhone 3G Contract Signups Prior to July 11th?
At least one O2 rep has been telling customers that they will be able to sign up for contracts and rate plans ahead of the 3G launch to help expedite sales on launch day.
The main point he told me was this, From July 1st All O2 stores in the UK will offer pre registration Credit checks, You can come in store, have your contract setup for you, and a unique registration code given to you. The contract will simply be "paused" and wont be activated. No details are taken about which model phone you are going to be purchasing.
You can then turn up on July 11th and quote the registration code and then make a standard purchase of the phone and then the contract will become activated.
