Nice find, Rob.
Exsp...... Be careful buying an Apple device in the USA ad they may be locked to one carrier. Here in Aus they are now sold unlocked, but USA May be different.
Another useful app (besides Viber, which we use a lot) is Heytell. It us a voice messaging system, where you can send 30 sec voice messages. Useful for slow typists like me. Both parties must have Heytell downloaded and installed.
