What I do is go into the Market and find the apps that automatically download and uncheck "automatically download updates". That's a start. If they end up installing, just uninstall them. Also go through your apps. I had a bunch of updates that failed because I had low phone storage. I went into my Hotmail and cleared out 16MB of memory!!!!! That surely got me more room in my phone. I do that with the e-mail and Facebook, just clear all data. Yeah then you have to re-enter your email and paswords for both but it's worth it to clear all that data up. So just try clearing all your apps' data (ones that have a few MB). It's working so far for me so I thought I'd pass it on.
