I have an ipod touch (1.1.4 16GB) and a couple of days ago, all my safari bookmarks were gone. Ever since then, when I add a bookmark it deletes itself within 10-15 minutes. My recent history, cache, and cookies are cleared as well. If I login to a website, it will only last a couple of minutes before logging me out. I have no idea why this is happening. Anybody have ideas?
