I'm still on 2.1. Now, I have all of my music and videos synced, and while that won't take that long to reinstall, all of my jailbroken stuff will. Especially my ROMs, OS 7.5.5 (300MB disk drive. >_>) and not to mention all of the apps I have from Cydia. Plus, I'm on mobile broadband with a 5GB monthly bandwidth limit. If I go over, I get a huge fee, so downloading 250MB is huge. Is it worth upgrading to 2.2.1, or not in my circumstances?
