Help... Flash or Ram allocation for Mogul

[Sellinghomes]

Hi all,
I have the mogul and recently upgraded the software to CE OS 5.2.1629 Build 18136.0.4.8.

Since doing this, my phone has actually gotten slower. I want to know:

Is there a way to allocate some of the vast unused storage memory and move it over to the computing side of things for much more computing power?

I store everything on a storage card, so I am basically not using most of the Ram potential. Sprint said there is not any way to re-allocate this, but I figured someone out here has a hack or solution that will work safely.

Any help would be greatly appreciated?
