Hey guys, first of all, i am a totally noob in purchasing handphone.
But i am kind of interested in getting this model since there i already asked for a recommendation in the specific thread and got a response to buy this model

So i would like to enquire, what should i ask when purchasing this model at a handphone shop?
Just afraid that i might get cheated for broken items, or got charged over-price.
What is the range of price that i must expect from this handphone?
Do i need to switch my sim card to cope the phone's features?

Battery life only last 4 and a half hours?!
And i am thinking that it will at least last 2 days with a little shooting with the camera.
Can anybody kind enough to confirm the battery power of the N82?

Much appreciated.
