I am o2 with Carphone Warehouse and last upgraded in March 2007. As I last upgraded prior to 18th Sept 07, I was hoping to get my authorisation code from CPW and leave. I purchased an iphone from the Apple store this morning and rang CPW to get my authorisation code. 3 different departments tell me that I can only have an authorisation code if I purchase the phone from CPW - anyone else have this problem? Bear in mind I am still in contract but am relying on the following from both the o2 and CPW websites: If you became an O2 customer or upgraded on or before 18th September 2007 You can switch to an O2 tariff for iPhone without paying any remaining monthly charges on your existing contract.
