My N1 was sitting on my desk 5 bars 3G and wifi on. I went to send a text and it failed. Tried a diff number and it failed. Tried making phone calls and nothing happend. Turned off the wifi and noticed I had 5 bars but no 3G or E symbol. I just got a network error when trying to access web pages. I rebooted the phone and it was fine. This is a huge huge problem. If this happens I will not know it and miss important calls, sms etc Still got data on the wifi. If this happens again I am going to have to switch back to my trusty iPhone. As much as I want to love the radio software/reception has some serious issues. Based on research on the forums I don't think it is my unit thats faulty esp since a reboot fixed it. It will be curious to see if others have this issue. I realy hope HTC/Google releases a better radio FW for this device or its going back within the 30 days.
