I just purchased a 2g touch. Would this app be useful if only over wifi or is it more for a data plan app? Sorry new to these apps, thanks
It's alright over WiFi (not worth 16 bucks). I think it's much, much better over EDGE/3G (definitely worth 16 bucks). It's best and most reliable, for me at least, for IMing on the go. I don't think I'd buy it if I could only use it near WiFi. I usually already have a computer for that which is still much faster and much more efficient. But you can't beat it if you're on the go and want to keep up with IMs.
