On my 3g iPad i now use the textfree unlimited app, wich gives me a free cell number to text and recieve texts from anyone and anywhere. I also use the fring application and run Gizmo 5 voip on it (it's free) i pay $20 a month for 500mb 3g (Telus, Canada), so i can call and text and recieve calls and texts anywhere i go for only $20 a month, it's great.
