I had some problems after installing some packages and i decided to reflash. After i backed everything, i reflashed without problems and the device booted up without problems. But now, the device won't take any sim card i put in it (the sim card i was using wasn't removed from the device during flashing) and instead of showing the signal it shows the no sim card icon. My sim card is working ( i tested it on a n95 and a nokia 1680 and it works) and i never had used the pin to use it.

Is there anything i can do to fix it? Is there any way to troubleshoot this? Or should i return it in exchange for a working new one (i bought it last week) ?

Any help would be appreciated.
