    Default Hissing sound from the back of my iphone 3G

    Ok i know this sounds like an extremely paranoid question

    i have recently bough a new iphone 3g 8 gb

    i unlocked it and ofcourse JB , 2.2.0 /2.28

    i have started to hear that hissing sound when i used a sim by a network provider that isnt the one i bought it from ( then again i only used the phone for like a day or so before ) , its very low but its there , its not consistent its like hearing a fax modem connection , although the phone worked perfectly ( there are occassional lock ups in some applications most of them are 3rd parties ) , when i removed the sim and entered one that is supported by network that the phone was intended to use there is no hissing sound so i can pretty much say its sim related , i still am doing some testing with phone to see if the issue would appear with this sim .

    so wut do u think ? did anyone experience this issue with a sim card before ?

    thanx in advance

    At Laaaaaaaaaaaaast i figuired out what causes the noise , please do the following steps and tell me you feedback to know if this problem is unique to my phone or not

    1) set brightness to Auto
    2) press the power button to turn off the screen
    3) cover the light sensor with ur hands , the whole upper part
    keep covering the light sensor through out steps 4-6
    4) turn the phone on
    5) enter the lock key if u have one
    6) Put the back of the phone on your ear an tell me if u hear a noise ??

    when i turn on the phone in a lighted area there is no sound , but if i turn it on in the dark the sound appears , could be somthing wrong with the backlight or sensor dunno
