Hey guys, I'm new around here so sorry if this has been answered before. I'm planning on getting an Android phone soon (can't decide between the Moment and the Hero if you're curious) and I'm wondering if there is an app or a way to use different apps to talk over Wifi. I don't get good cell service at my house and just want to be able to call/receive at home. I have a google voice account and Skype unlimited (but as I understand it, the current Skype app only works on the 3G network). I don't mind it using my cell minutes, I would just like to be able to talk and send/receive messages. Thanks!
