This service will extract and show you phone numbers from Windows Mobile pim.vol file
Right now service is quite buggy, but you still can get a reasonable result if you have no other option. :-)
Just upload a file, and in seconds you'll get contacts list (maybe with some crap between them).
Please note that currently only processing of files up to 3Mb in size is allowed in this free version. I can process a bigger file for you for just $29, feel free to contact me.
Have fun! http://drumrock.ru/
