I've had 450-500 talk minutes for as long as I can remember, and I only went over once(and that was when I was w/ ATT and had rollover to cover it).
And isn't there an official Google Voice app for iphone now? Even though I don't think it's be as nicely integrated as in android, you could use that or TextPlus(?) for texting. I used both when I was on AT&T to get by on 200 texts/month.[/QUOTE]
my rollover minutes on ATT were maxed and expiring, I never used them at all.
I used google voice for texting on VZW for sure; pisses me off when someone texts my regular cell and costs me money. No matter how many times I tell them though, they never listen and keep using the wrong #.
Last I was on ATT, there was no official app for google voice, you had to jailbreak. But this was almost a year ago (May 2010). The rumours was there was an official google app for voice, however, it never got approved by apple... it was leaked and made available through jailbreak if I remember correct.
Edit: look like an official app showed up around last November.
