7650 memory problem

Does anyone know, how the 7650's user memory chip can be replaced. I mean replacing it with a bigger one (8 or 16MB instead of 4)??

Thanks in advance! Panza

I do not think that this can be done... It would be alot of work for only 4 or 12Mb.

For the cost and effort to do this it may just be worth getting a 3650 where MMC sorts this problem.
