I had the 8830 from vzw and big dis. No mms,no gps,small amount of minutes. I gave it back. I will wait for hopefully some type of blackberry with wifi so I can use my router with it at the house. And if that doesn't happen withing 1-2 months I will get the 8800 from Tmbile. Gps does work/mms does work. P.S. I have Don't Use Sprint and Stay away from Sprint Nextel painted on my car windows>hee hee.
