maintaining history in mobile

[him jain]

hi..

Can anyone tell me how to maintain history of the previously entered details could be stored in mobile?
e.g. i run application and i enter mobile no. into it
and when i again run it, it should show the previously entered phone number also.
basically i want to implement cache functionality in moy mobile.
if anyone has any material regarding this or any information, please reply asap.

Then you have to store data in RMS for caching
