When you store numbers into the E61, MAKE SURE you store them into 'tel (business)' or 'tel(home)'.
DO NOT store them into the default 'telephone!'
WHY?
Because they do not SYNC with Outlook and you loose the numbers. So always REMEMBER to choose the TYPE of number and NOT USE the default 'telephone' setting.

PS: Also peeved about not being able to open jpeg attachments when using Blackberry Connect on the E61.
