Hey I had a nexus s for about a couple months now and I've had some recent problems the last 4 days , when my service has just stopped I called koodo to ask what was going on and they told me that I have service when I checked my phone it says I dont have.service. & there is a little x above the signal bar. I've phoned in and they said the problem wasn't on their end.. so I checked again and it was set on airplane mode. I clicked but the mobile network area stayed grey and it just went back to airplane mode. I've reset and even rooted n its still like that .. HELP.
