Default Just throwing up a idea for discussion...

Please Login to Remove!

I wonder if it is possible to add a special program that can load programs off the media drive? That way, we can have more programs loaded without cluttering space for run time and storage for emails, log, etc?

Granted, this program would have to be a "loader" program that somehow knows how to copy programs off media into internal memory then runs it? That is, assuming that internal program has enough memory to do that in first place.

You definitely need to add some more details.

Because the BlackBerry OS doesn't work like that, and the BlackBerry OS cannot be modified.

FYI, jfisher is a pretty experienced BB software developer around here. If he says it can't be done, I'd likely take it to the bank.

Software developers can only access certain parts of the BB OS that RIM decides they can access (called API's.) It's locked down by RIM for security reasons.

just to be clear about this, the blackberry is java based and applications don't sit in a file structure like they do on windows devices, there's no executable that sits in a folder somewhere that can be accessed freely. the apps are referenced by metadata that is built when the apps are installed ota or via usb and go through security checks. a lot of misunderstanding comes from people (through no fault of their own) who are used to pocketpc or windows in general where you can hack resource files and everything is generally less managed and does sit in files that you can move about as you please.

from the developers guide:

Connecting to an application on a SIM card
For BlackBerry® devices that operate on EDGE networks, you can create BlackBerry Java® Applications that use the APDU and JCRMI APIs defined by JSR 177, to call the methods of an application on a SIM card. You must use the BlackBerry® Java® Development Environment Version 4.2.1 or greater to create a BlackBerry Java Application that uses the APDU and JCRMI APIs.
The APDU API enables BlackBerry Java Applications on a BlackBerry device to use the APDU protocol to communicate with an application on a SIM card.
The JCRMI API enables BlackBerry Java Applications on a BlackBerry device to use the Java Card Remote Method Invocation protocol to communicate with a BlackBerry Java Application on a SIM card.
For more information on creating BlackBerry Java Applications that support JSR177, see The Java Community Process(SM) Program.

is that the micro java support for card technology? does it allow writing on an sd - not sim card? and finally - the apps need to be specially written to use the api... this doesn't tackle the issue at hand; a general application management tool, and is only loosely related.
