This is the best phone in very best price. It is easy to use and very slim even we cannot feel that we have a phone in our pocket. It has many features including MMS, GRPS and we can upload the ringtones, wallpapers, etc, from our pc using the datacable.
The secret code of this phone is "2945#*#". If you write this code from the keypad then the secret menu appears which has some exciting and secret submenus. I will not take any responsiblity if this code damages your phone and/ or does not work.
Now there is the procedure of writing this code:
On the screen write this code as 2945#*# and the secret menu appears which contain seven submenus. Through the submenus you can adjust your contrast , ringing volume, vibrator value and backlight value. If you write the digits 8, 9 and 0 between the * and last # then another secret menu appears and it has some great submenus and settings which can only be understand by any cellphone engineer.
Now the B2050 also come with the FM radio options as B2000 and the secret code also works in B2000.
