Just upgraded to 2.2 firmware and found it lagging. first when i took a screenshot, it lagged. the entire touch screen wasn't working. waited about 10 seconds and it came back. I was typing my log in details for the Facebook app, and I used the magnifying circle to go back, it lagged. it went away, but the magnifying circle remained there. Just beware, maybe a reboot will purge this lag. Anyone else with similar experiences?
