There is ROM and there is RAM. You cant install programs to RAM.
Here is why:

RAM is short for Random Access Memory, RAM is used to run certain basic programs and functions that your PPC needs to operate correctly, and functions only while the PPC is receiving power. Programs you're using are written in RAM temporarily while the PPC is processing them. Think of RAM as a playing field, a large open area where your programs function. Each program takes up a certain amount of space; the field can accommodate one or several different programs at one time, but its capacity is limited (not so much on Sprint touch pro ). When you shut down a program, it disappears from RAM and (ideally) the space it occupied can be reused but WM won't properly relinquish the RAM space even when a program is closed. However, because stuff in the RAM is retained only while the PPC is powered up, soft reseting will always clear the RAM.
