The mobile may have 260k, but remember that some of that is going to be
taken up by the ROM image of your application. So, if you're using 150k
of heap, you're only leaving 110k for the ROM image and stack space,
which isn't very much at all. Emulators based on the WTK always have
512k for their heap so you're hard pressed to use up their memory.
I would say first off go through your code and reduce that heap usage.
What are you using 150k for? Seems that you should put some of that data
into RMS or else let it go 'cause that's way too much for almost any
handset to handle.
