LG Wireless Phone

nokia n76 camera does not start!? i bought my dream phone from a friend. hmmm... it is so akward, why? here in Manila, brand new Nokia N76 is out dated... but why? it is a later version compared to n73 or n70... but why is this so? i call Globe Telecom, Smart COmmunications and Nokia Philippines, and they say N76 is "phase-out" .Whenever i go to SM malls, like in NOrth Edsa and San LAzaro... they do not sell n76... hence, n70 and n73 are still available! why??? here's another thing,,, what do you think is the problem? my n76 has no defect.. except for it's camera.. it's not totally damaged however, it does not start.. whenever i run my camera it goes back to menu? what do you think is the problem? flex? or camera itself? because THAT'S THE ONLY DEFECT... I CAN TYPE MESSAGE AND EVERYTHING....pls help
