i dunno if amtel avr kits for this project are available in india or not.
secondly, i think it'll be difficult to implement the project wid native BT support. i suggest you use BT com port emulation using the rs232 communication interface protocol (what most BT dongles use to communicate wid the phone) that way the task will become easier for you. the commonly available PIC series uC has internal rs232 IO (which i guess you know

) which can handle this for you. other than that you'll hafta learn how a j2me code can send rs232 commands.
at the moment this is all the advice i can offer you. lemme check out if any of the my frenz haf done a project like this and get back to you
