I've flashed back to 2.0.1. I've done this numerous times historically and the 2.1 OTA update always took awhile to download and was 60+ mb. I noticed this time it notified me much quicker that the system was ready for an udpate, so I went in and the 2.1 update is only 15mb. It says 2.1, and the description is for 2.1 - what's up with the 15mb? Should I let it go forward or reflash?
