On the mogul,there is no mystery what needs to be done. You need to get a chip with twice the memory. The problem is,there is no chip listed in the Samsung catalog with the proper specifications. The ram is contained in a mcp (multi-chip package) along with the flash rom.

This does not mean that such a chip does not exist,in fact it is suspected that the vogue uses just such a beast.Samsung will in fact make any combination you want. (if you are willing to buy 100 thousand or so) What we are missing is a good high res image of the vogue so we can verify this and get the number off the chip. Once we know what chip it is,and can find a source of them,then its just a matter of putting it in. (assuming that the board of the mogul is wired for the larger chip,which is not certain) This requires a degree of skill,and some equipment that may not be part of the typical hobbyists gear.(it is however readily available)

There is however one additional issue. Since the rom is contained in the package as well,and must be replaced at the same time,the chip will need to be programmed. This can either be done prior to installation or it may be possible to do so after installation if a jtag port can be found in the phone. Its probably best to do it before hand however. This will require an appropriate programmer to be procured or built.

As you can see,the issues are known,and potentially solvable,but random poking about,swapping chips and bricking perfectly good phones will not do the trick.
