Write a program for the Nokia 7650, which once installed, could receive latest firmware via bluetooth and install it in the phone.
Physically remove the flash memory installed in the phone, replacing it with a larger flash memory chip, stolen from a mp3player or something (hint - the nokia 5510 has a 64Mb flash chip in it).
Allow the 7650 to run Symbian Series 60 OS V7 (as in Nokia 6600)
Explain to me (and the masses) why there is a 15Mb ROM drive in the 7650 (Z and what it does...
