Hi, I just bought a my touch 4g, which is my first "smart phone". A bit overwhelmed to say the least but fascinated. I will be asking many questions over the next month I am sure!! With two kids I don't have many opportunities to sit and play with the phone so it will be a long process to figure this thing out. Fun to be had! My contact were copied from my last phone and they are an absolute MESS! I need to delete 70 percent of them and rename many. My last phone jacked them all up. I think this would be best done on my computer.... how do I do this?
