i didnt make a downgrade, how could i do that? "3.2010.02-8" thats the latest firmware there is, P1.2 is still not there! But as i said i have hatd these sim card not recognized problems from the start (dec 2009) only then not that often and mostly fixed by a reboot, now it seems it is really broken. So i think it is hardware anyway, i brought mine today to a Nokia Care Center and they will mail it to nokia, just now in a different waiting game then before.. Now on my N900 to return else waiting for 1.2....
