I have both a 3G and 2G iPhones (both 8GB), with the intention of selling one of them. Both are nearly new, especially the 2G iPhone. I am on a proper iPhone tariff with o2 (UK). I much prefer the way a 2G feels and looks. What would happen if I had a problem with the 2G iPhone, and wanted a replacement from Apple etc.? Seeing as i've had a free upgrade to the 3G iPhone... Which would you keep and why? I'm really not sure what to do. Cheers, Mark.
