It is possible using the location API defined in JSR-179 but its supported only in new phones..
Its also possible to get the cell id i.e. id of the network tower using System.getProperty("cellid")...

You cannot directly specify the drives such as C: in j2me i suppose.. check the PDAPDemo in the wireless toolkit examples.. It shows how to access files and manage them.

Dude.. IMEI number is very much different from Cell-ID.. Cell ID is the id of the tower that takes care of network in your area.. IMEI number is a specific id for each cell.. Its just like MAC...
