Isn't it weird how some people will have all kinds of problems and some don't. Mine has been working great since i got it awhile back. no problems with receiving or sending text.. Been working real great lately sending pictures by text and to facebook. Only problem I've had is the battery, but i think that world wide...lol
Kinda glad for your post, as I've been expecting my (unrooted) Revo to have the problems described by so many others.
Main functioning problems:
1. Stalling during boot: This happens whenever I don't give it enough time to boot up, and touch the screen or buttons "too early". Now I wait at least 10 minutes.
2. Stalled phone when using GPS for a while. Don't know why as of yet. Now I also travel with my stand-alone GPS, with its outdated maps and lack of live traffic. Not nice being in an unknown area and having your GPS tank.
3. Lag, lag, lag. The vaunted Android OS memory management doesn't work well for me. The phone can go down as low as 45MB of unfree'd memory. Solution: Task killer or memory freeing (got tired of selectively killing processes). Secondary solution: remove widgets. Tertiary solution: remove apps.
4. (User error, but scariest) Too many apps in internal storage: Symptom was a reboot cycle after about 2 minutes of use. Fixed without hard reset, but lots of patience in deleting one app per reset until I recovered enough internal storage.
I swap out batteries just about daily, so those frequent reboots also help. Gotten used to the extended battery's size, for the tradeoff in runtime.
