As the title says... using my phone one minute - no SIM card detected the next. I've tried the usual put paper/tape behind it, reseat it.. even tried an old SIM card lying around and it won't work.

Could this be a software issue? Tell me its a software issue? :'( I'll reflash if it is.

I basically spent about 2 hours taking the SIM cards out, putting them in.. but it simply wouldn't recognize anything...
