oh geez...I got on XDA where someone had posted the new .Zip file for the 4.0.8 update. I tried to manually update it and it didn't work either. When it came back up, it said I still didn't have enough space. The low disk space error wasn't present before I shut down. This is stupid. I guess the only other thing I can try is a factory reset, and do the update before I add any apps or set anything else up.
