On occasion when I am trying to search for a contact in my address book I get a error message that reads "Input system error: restarting system".

Anyone else getting this? This is my second unit the first one was replaced within a month due to the hour glass flipping on the screen for 45 min.

Any help would be great.

My 7105t (OS 4.1.0.309) was giving me this error every time I turned on suretype, it was defaulting to multi-tap for some reason. I read in another thread that its probably due to a corrupted database; I restored from a backup and everything is back to normal now.
