I did a search on ipod touch for gps and noticed it goes not have gps built in like the iphone. I did however hear of a craddle adaptor of some sort? One of my dads friends is an avid golfer and is ready to go out and buy an iphone just for this feature but already has an ipod touch. What are his options? He has Verizon and wants this bad enough to switch, pay etf, and get an iphone. However if there is some way to do this with his touch he is willing to buy an adaptor. I believe the app is called GolfLogix. Thanks. PS- would another alternative be a used iphone and just get a data plan on it? Is that even possiable?
