I think he means the whole call log... I found this a pain too.
The only easy-ish way to do multiples I could find was to change the options of the call log to email and delete via messages folder.
Pretty tedious still though, surely theres an easier way.
Go to the messages icon with it open press the bb key then select view folder, then select phone log and then it will work like the messages double tap to select multiple messages and delete prior etc.

I cannot even delete the call log, one call at a time. I have shown no new calls in the log for 2 weeks and when I try to delete, I get the following message: "Uncaught exception: java.lang.NullPointerException" Anyone know what to do?
