My excitement about the new iPhone has waned over the course of the day as I've slowly realised that O2 customers have a difficult choice to make. My understanding is that the iPhone 5 released on 21 September will never work on the O2 LTE 4G network. It seems O2 customers have to decide whether to buy next week and get phone that will never work on 4G or wait for an unspecified time (probably many months) in the hope that a new O2 4G specific model is released. My heart is sinking and I honestly don't know what to do. I've had my heart set on buying the new phone on launch day and O2 is the only choice for me. However, I'll probably keep the iPhone 5 for up to three years and can see me regretting being stuck with 3G when the world has moved on. Is my understanding of the situation correct? Are others also wrestling with this?
