I love the iPhone and just got the latest 3Gs. Heaven! Almost…
When traveling I paid $60/month just to keep my number with AT&T and rarely used the number. As long as you can get connected with wifi, you should be able to use:
VoIP
Text
What are some of the services that exist? Let’s take a look:
VoIP –
Skype
> Does not offer service for 3G, this is disturbing to me, I hope they have a release announcement soon!
TruPhone
Fring
Text –
TextFree
> Costs $5.99 for full version and sends texts to/from email
Google Voice
> Not an app and not yet listed in Google Apps for iPhone but promising from-web texting
So, in the hopefully near future, the iPhone will be able to be used strictly with wifi connections – no more expensive phone plans and international calling plans!
