I did a search but couldn't find an answer to this. I recently received my first iPhone bill and had an overage charge on texting. The only person I text really is my g/f. We both share a family plan, and I was under the impression that we had free m2m. So i was checking my usage this month and I'm already over on my Texting, so I called and AT&T told me that the iPhone doesn't have m2m unlimited texting. The next upgrade was for $15 to 1500 texts. My overages only totaly about $5, but how come no m2m texting, but m2m unlimited minutes for the iPhone? Or no upgrade option less than $15?
