The Treo 650 has a special type of hard reset called "zero-out reset"
which does the following:

[ http://mytreo.net/treofaq/Treo650Resetting ]
"A zero out reset will regress a device that has non-volatile memory to
its factory-fresh state. When done correctly, it completely rewrites
your device's internal memory with zeros and ones, ensuring that any
data is expunged."

Is there an equivalent way to rewrite a Treo 600's "internal memory
with zeros and ones, ensuring that any data is expunged." ?
