Apple, FaceTime is awesome, may I suggest TalkTime?
FaceTime is truly awesome and I find myself wishing that everyone in my family had an iPhone 4, but part of what is so great about FaceTime is the fact that once you start it, it takes the call to WiFi, and at that point, the chance of AT&T dropping your call vanishes.
This got me thinking: Why not do the same thing for audio alone? You start a call, you switch it to TalkTime if both parties are on WiFi and you stop worrying about AT&T dropping your call.
I know this sounds a lot like t-mobile's @Home service or AT&T's MicroCell, but these cost extra and require additional equipment. FaceTime doesn't and TalkTime shouldn't either.
