Sorry for not providing the debugging info. I'm attaching two files along with this mail:
1. identify.log -- the debugging output for 'gnokii --identify'
2. getphonebook.log -- the debugging output for 'gnokii --getphonebook ME 1'
'gnokii --identify' does not show any error messages. It shows the
phone model number, etc. I have included the output just in case it is
required to figure out what the problem is.
