is there any section to find out which mobile model belongs to which OS.

for example:
N73 OS9.1/9.2 I guess so....

in similar fashion all Mobile models should display the OS.

if there is no such section please include the section to find out Which mobile model belongs to which OS

the other easy option is for you to search via google to check the kind of OS your mobile has and then check the threads. a lot of people do that too! thread will now close.
