2 days ago, when I tried to make a call, it started to display "General Error".
I can't call and send SMS, but I can receive them.
I changed the Sim, reflashed, clear device... but it doesn't work.
I bought my N900 from Nokia online store, in UK, free sim.
Finally, I searched on Google, lots of people have the same problem like me, one could fix it but I can't contact him, the rest couldn't.

edcarsky said he could solve this problem, so can anybody show me how to do it please?
