Nokia N91 default songs-details

either it is listing songs you uploded since you may have not uploded a single so it is empty or data connectivity problem so no list of songs get loaded

dear sir i am using nokia 3110 from last 1 year,but now i am facing problem in it,it is getting automatically switchedoff after few minutes.

The default code for nokia is 12345, if that does'nt work you will have to call your service provider to have them reset it.

format using *#7370# default security code is 123456...

Update the firmware.
Reload the songs.
If the problem persists:
Re-rip the CD songs in Mp3 format in Windows Media Player
Then reload the songs. WMA format has a checkable option that is normally turned off by default, but must be turned on inside your Windows Media Player - it is much easier to reconvert the songs into Mp3 format than to tell you how to change this WMA option.

-Tha Mp3 doctor

suggest me what are the external softwares supported for NOKIA N91 4Gb

Use Windows Media Player to transfer the songs - you will actually have to tell Windows Media Player where the songs are on your computer, because it will only search in the My Music folder by default. Microsoft.com has detailed help files for performing all of these operations in Windows Media Player - just enter "Windows media player help" as your search term.

Not enough memory means your phone is too full of data IE. Pics, Themes, Contacts, Applications, Games etc...
The phone needs a certain amount of memory to function.
When sending files via Bluetooth, some useless files remain on your phone these have to be deleted manually.

files sent by bluetooth go to the phones own memory. You have to move them to your memory card manually, you may have 2 copies of some files , 1 in memory and 1 on the card.

VIRUS. the only one problem for such phone make you mobile phone slow . damage your software , resart your phone,and even use your battery and reduce your talk time so the solution is flash your phone or reset your phone to factor setting and that will make you lose your personal data .. the only solution
