are you sure about that? usually stuff like that will wipe all your  
saved data. the next thing is that it is usually necessary for a  
firmware upgrade that a cell phone won't go out because this could  
wipe your telephone (cut off electricity while flashing the phone new).
and if they could - this would be great. no more hazzles if you need  
a firmware upgrade. usually you have to backup somehow your data  
which isn't usually completely saved on a removable medium thus it  
isn't usually possible to back it up completely. then you have to go  
to a store who will keep the phone for a day and let you pay (in  
Germany) ca. 25 Euro (ca. $28, or 3000 Yen).

except for smart phones this will be very hard and i do not think  
that it will function with a java-program
