Hello All, So I'm getting the iPhone 4 on launch day through o2.' My mum gets free upgrades, as she's on a really high tariff and gives them to me. But im only on pay and go. So o2 are saying that iPhone is only available to existing customers, who are looking to upgrade. That's all and well, as they'll be more iPhones going around for the existing customers, and i know as my mums upgrading she'll get one alright, but how will that affect me when I have to get my number transferred over to a micro sim, I'm quite wary of this, as i don't want to be stuck with an iPhone and no sim. Thanks in advance for any comments. Caolán.
