I had signal but a few of my texts were failing in 60606. Now in 60607 I have no signal. I even went out side and walked around the block. No bars, no service. Tried restarting the phone twice. Nexus S 4G. WiFi works, but 4G doesn't connect either. I had a few brief seconds where it flashed 2 signal bars, but ithat was it.
Edit: This is still occuring. Is there a tower down or something? I can also confirm the same issue with an HTC EVO Shift.
Edit2: This morning both phones had normal signal but as of around noon today (central time) we are back without service.
