can games/apps communicate between an ipod touch and a iphone? such games as words with friends, can that be play with an ipod touch on wifi with an iphone? i plan on buying an ipod touch for such things as games/apps/music since i already have a phone (not iphone). pls dont suggest getting a iphone since i'm very happy with my phone (g1). i wanted a seperate for those other things so i can dont have to worry about battery life. i was just wondering if all or most apps/games that are made to communicate with other devices will work fine between ipod touches wifi and another iphone or ipod touch wifi. i tried searching but putting in ipod or iphone seems to be mute in this section and i didnt know how to word it easy enough for a search.
