you can reflsh the firmware on the phone and that should correct the issue that you ae having with your camera.

you should do a factory reset, this will blank all info and data in the phone...if that does not work, then you may have to take the phone into a mobile service center and have them reflsh the firmware for you.

you may need to look at the sim holder see if the prongs that read the sim is to far down you can try to pruy them up a bit....the place the sim back into the phone and see if it reads.

2 - you can reflsh the original firmware back on the phone...you can go to www.topsony.com and download it from there...this is a pay site.

3 - if none of the above work then you will have to buy a new mobile.

first reflsh the firmware on the phone....if that does not work you will have to get a new phone board.
