I used Virgin Mobile from 2003 until, well, a week ago, when I broke down and got an iPhone.

They have some pretty good plans, some of which include unlimited texting.

If you'd be interested, I'd totally be willing to mail you the phone I last used, with wall charger and car charger, for the cost of postage. It has a keyboard, and still works pretty well.
