Check SIM error
Anyone have a problem with their phone telling them the "Check SIM" for no apparent good reason? I've had my phone for 2 weeks and have gotten the error at least a half dozen times. I'll just be sitting around and all of a sudden my phone will beep at me and display "Check SIM". A power cycle of the phone seems to fix the issue. What a hassle.
I have the Navigator service, but I don't think it's worth it. It makes an already short-life battery even shorter. Go here to get google maps for your phone: http://www.google.com/mobile/gmm/stp-js.html
