scratch that - I removed Facebook as a system app and restarted. It gave me 18MB of ROM back that I used to convert the APN app (would be nice to free up more though.)
Now I have a new problem: my phone won't open it's data or GPS connections. I've restarted twice, and made sure that data and GPS are actually enabled, but neither the 3G icon or the GPS 'target' icon appear in my information bar, and I can't use either one. I manually entered my APN's first, and they didn't work, so I restored from my backup, but those didn't work, either. What can I do?
