Sorry for repeating the message. I do surf some web and understand that not all palm devices have the serial number. I got this error may be due to the palm device does not have the serial number (i've tried oredi by simply retrieving the number from the palm device). In this case, the code of retrieving palm serial number does not apply to this case???? So how are we going to verify the application where we need to extract someone's palm serial number for verification?? (sorry for bringing up this issue since i know it's been discussed for quite some times but yet, i'm not able to find the discussion)
Any idea of it???
