What plan do you have? I have the Sprint 15.00 unlimited data plan. I was thinking about adding texting, but then figured who would I text. I mean I can access the instant mesg. on the phone and use yahoo. I was also thinking about the navigation pack, but with things like live and google maps and then when amaze finally works.....I just don't know. I mean I like the fact that the navigation will talk. Any thoughts?
