I believe it started when I was downloading a lot of apps, trying to find a task list widget I like. The Pure Calendar App said it would work with a modified version of Astrid Task list, which I downloaded from their site and installed. Ever since then, even after uninstalling Pure Calendar and the Modified Astrid, auto rotate still won't work. Have I screwed up my phone? I found another thread where a person said doing a factory reset fixed it. But I have a LOT of apps, a number of which I paid for, will a factory reset make me lose all of my apps? I mean, I know they'll be deleted, but is there something on the sim card or something that remembers which apps I've downloaded, like the downloads page in Android market? Or will I be starting from scratch (paid apps and all)? Or has someone found another solution that fixes this?
