What's the easiest way of switching on and off the web client? I'd like to have "phone only", unless I'm traveling. (The spam is wearing me out and Verizon offers no filters!)
Removing the service books only prevents you from sending email. If you want to block email coming in, set up a filter and don't forward it to handheld in BWC.
Logon to the BWC
Click Filters
Click:
Specify what email is sent to your handheld and control notification using Filters.
Click
Default when no filters apply: Forward messages to handheld
Select radio button
Do not forward messages to handheld
