Any web host does automatic upgrades?

I signed up with a web host and installed WordPress using Fantastico. But Fantastico installs an out-of-date version of WordPress. Worse, when I tried to add RSS feeds, one of the feeds didn’t work but showed my username and directory instead! And my web host won’t help me upgrade. I will have to do it myself. But I have no technical skills. Is there any web host that does automatic upgrades? Does Dreamhost or Living Dot do automatic upgrades? I read about the WordPress plug-in that does automatic upgrades but I don’t want to take chances because if it doesn’t work, I will have to reinstall WordPress myself.
