cid49 or 36?

How can I find my k750 is cid49 or cid36?

its simple... if u r havin the DCU-60 cable get Phone -XS++ and just connect it will give information about your CID in the status messages...after getting that CID u can disconnect phone-xs++ no damage done :)

if you use phone xs or xs++, you'll get something like this

you can know your cid just by looking at the top bar.

can I use far manager?

far manager does not support cid49.is there any way i can get it itsupport cid49

You can do it simply by pressing >*<<*<*12 and in ITP software section
there sould be code like CXC XX_XXX_49 R1C. Last two digits are CID number
