The M5 I recently purchased has the DICE hookup for an IPhone/IPod/ITouch. However, I do not own one. Any suggestions on what to buy? Admittedly, I do not keep up with Apple or their products. Since I have a BB, I doubt I will spend the money on an IPhone, so any suggestions on what type of ITouch to buy would be appreciated. I am leaning toward a used one on craigslist but really dont know what the going rate is for the generations/setups. What do you all have out there?
