what's the best way to get online regards with the Touch? I'm constantly out and about with my touch when at times I'll need to get online. Say to access maps and find directions or something online. Normally I'll drive around looking for a wifi signal with my touch in hand. Sometimes I get lucky. If I'm in familiar terretory I'll know of some wifi home networks and park in a residental st. Even now I'm parked by a house with wifi. Low signal but wifi nonetheless. I'm sure some of you run into a problem like this, perhaps not as dire but it's still a drag. Does like a wifi finder thing exist or what's an alternative? What do you do?
