For those of you in the UK, you may be able to answer my questions. What is there difference between buying an iPhone from the carphone wearhouse and the o2 store?

If you have any problems, would you deal with them through the CW? The reason I ask is that I have heard from friends that the carphone wearhouse dont have very good service and there more interested in swiping your money than anything else.

im trying to deside if its worth buying from CW if they have stock before the o2 store or not.
