hi there. i have a problem with my N70. The fone worked fine for the past 2 months, however just a few days ago it went into "offline" mode and refuses to switch back. everytime i try to change the profile back to general or any other, it says "insert sim" now i have checked my sim in other fone's and it works fine. its definitely a prob with my fone. also i reset it using the 7370 code.. still no progress. please advise.. im losing my mind over this fone !! thanks
