midlet running in the background

[Tor Henning Post]

I wonder if it is possible to have a midlet running in the back ground while the user can use the mobile functions at the same time.

I'm trying to figure out how to make a midlet that listens to an extern bluetooth adapter which shall wake up the midlet, send over a data stream which wil be temporarly stored in a fileformat and then transmitted over GPRS/EGDE or the UMTS (3G) to a server for processing.

It would be nice if the user of the phone didn't have to worry about this prosess.

Im new to Java ME i've tried to search around but i can't find information about this, so if anyone got any experience with similar tasks who can point me in the right direction i would be gratefull

thanks in advance
