The other day I happend to insert a MicroSD card into the phone at the exact same time as I had a call coming in. After this, Android went syrup and was totally impossible to use. Every screen touch took a minute or so to be recognised. I tried to restart the phone and even took out the battery for a while, but the problem persists. I can't even tap in the SIM code because the screen saver goes on before the G1 even detects the first digit. Response time on the "real" buttons (e.g. menu) are only a few seconds, but the touch screen is a minute or so. Do anyone have a faintest idea about what this is about? I have a G1, not rooted, with the latest updates installed. The microSD I inserted was mint from the store, 8GB.
