I'm thinking to implement some proccessing logic in a background mode for nokia phones (both J2ME or PersonalJava based).
With respect to this my questions are:
1. is it possible to have multiple applications(midlets) running at the same time while the phone is on (without any communication with external party)?
2. is it possible to send/receive data over http at the time when the phone call is made or the connection has to be released first?
3. is it possible to notify user by a sound or a phone ring programmatically ?

Thank you,
