I have a problem with my Google Nexus S. Yesterday I was out in the city and my battery meanwhile died and the phone shutdown. The next day when I charged the phone, I noticed that it is showing no signal even when there is signal. I've turned it off and on a couple of times. I also tried a different SIM from a different service and it didn't show signal either! Also I tired those SIM cards on a different phone and it works.
The big mystery for me is that until the battery died yesterday I made calls from this phone with no problems, and until now I never had problems with this phone.
When I go to Settings -> About phone -> Status I see that Network is show unknown and Service state is show out of service. Is there anything I can try resetting?
