Restricting downloaded size of the file

[Ransika deSilva]

Hi all,
I have sucessfully developed a mobile application where the user can get the details of the employees of a company.
The problem is, my application has an option where the user can search for all the names, so that all the names (1900+) get downloaded to the phone. I just want to know, whether I have to put a limit for the number of records, cause the small memory the phone is having might overflow. Could you please adice me on this, and if I have to do like that, please give me some tips.
Thank you very much in advance....
