Password protection for Ericsson T610

I have an Ericsson T610 mobile and I'd like to be able to lock it password protected, without turning off the phone. I think it supports java, I can connect it to computer via bluetooth. I need: * A keyboard shortcut that will lock mobile * When locked only the screen saver visible. * Option to automatic lock after a time * An option on menu to lock * An option on menu to change password (3 numbers) I may also need help to install it via bluetooth. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as a software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) Possible support on install. 4) If you find an open source solution for this, even better, otherwise you agree to have you work released under LGPL. ## Platform Ericsson T610 mobile
