If you just want to restart it there are lots of free apps around that will issue a restart command, equivalent to power off + power on. I've put one on my phone but can't remember where I got it from!
Facade from SBSH issues a reset command to ssave you having to power off then back on, and can add multiple days off calendar entrys on the Homescreen. It's not free but it is worth every penny just to allow you to view multiple days of appointments on the Homescree. I use it on my Vox with the Wings Homescreen.
