I'm trying to figure out how to get an iPodTouch or no iPhone to communicate with a regular iPhone.
So iPodTouch has BT which is good for 30 feet or so, but I'm looking for something longer than that. So WiFi would work if you have WiFi there, but what about the GameCenter?
This would be for very small amounts of data, quite like a tweet and I want an area of about 100 feet or so.
Another option would be a kind of repeater where an older iPT can be used to go through a waiter to get the distance up to 100 feet.
