There are firmware upgrades available for most models of Q. Only sprint's Q9c has been upgraded to a different version of windows mobile so far (there is one up the pipe for ATT's Q9h)
go to
www.motorola.com and click on support, and then there should be something to the effect of update your phone's software (can't check right not, PC's shut down due to weather)
or search there for "Motorola Software Update" that program will put the newest of whatever is available for your phone on it...
make sure to backup your contacts and any programs you want to keep before you do it.
