I have google voice and I have loved being able to text from any browser, including the thrive's browser. Especially if you're on sprint for your mobile servce, I would strongly recommend setting up google voice.

I have been using Heywire for sms. It does not do mms but it is excellent for sms. The person you send the message to doesn't need to have Heywire installed.
