exporting mobile contacts and upgrading .NET

I wanted to export the contacts from my Windows Mobile 5 phone. At first I looked at TBexport as given here. But TBexport needed a newer version of .NET Compact Framework. Checked out the procedure given here. That is, basically install it, restart phone, and then go to HKLM\Software\Microsoft\.NETCompactFramework and change the value of the 3.5 version from 0 to 1 and changing the old one's value from 1 to 0. And then a restart of the phone. That worked, but was not needed - PPCPIMbackup itself could do the job. The pib file is in zip format, so 7-zip etc can unzip it and extract the csc file from it, which is actually a csv file.
