I unlocked my iphone so it works on canadian network.

but when the first i time i made a call, i noticed that the voice volumn is very low if NOT using HEADSET or SPEAKER ON mode, even i maximized the volumn. it is because i jailbroke it or it is just the poor design of iphone itself? is any buddy facing the same problem?

Ok, maybe this simple question will fix your problem, did you take off the protective film that came with the phone? NO, you should take it, its blocking your earpiece.

did u take of the screen protector?? u can cut that part out if u dont want to take the whole thing off....let me know if that helps

there is a screen protector on the phone?, i thought apple claimed it was scratch resistant

seriously? that thin screen protector make such a difference? you gotta be kidding me. let me try. i let you know.

P.S. i seriously dont think anything is scratch resistant even somebody claimed.
