how much flash memory i can upgrade for e500?
and how much is 256 mg?

Did you ever get a response to your question? I am a new E500 owner and am trying to figure this whole thing out as well...

Thanks for any info you can provide, as I do not see a reply. Also, are you still using the device? Do you like it?

I did not get a reply. So far, yes I am still using the device. I had a problem with it dumping all my info, but finally managed to get it back. Be sure to set up automatic backup when you set your device in the cradle. It will save your life if the unit decides to reset itself.

I also had a problem with the unit forwarding my appointments by one hour.... needless to say I was late...

Otherwise, I am still trying to see if I can get a pre-paid SIMS card without joining a network for this phone.

How are you making out with yours?
