its quite difficult to fomat your phone becuase for formating you needsoftware tool box and lots of software files and drivers. But you can do one thing turn on your phone and go to setting and last option master reset.your phone will restart. befoe doingthis creat back up for your data.

it is not possible as the space in sim is only 32 or 64 k and can only same contacts and afew msg.

I am unable to open camera on my sony erricson W700 mobile and also, I am unable to search contact in the contacts folder through letters.

go to setting and look for master reset,press reset all,and the default password is "0000"

If you have forgottan the code you will need to get the phone flashed this will reset the code back to the defult of 0000 this is the quickist solution
