Sandy, in post #5 you imply that RIM has hidden this information. I direct your attention to this document found on RIM's knowledge base which quite clearly spells it out. Page 2 - "Overview" http://www.blackberry.com/btsc/micro...00%20733485502
The BlackBerry® Internet Service is designed to provide you with automatic delivery of email messages, mobile access to attachments, and
convenient access to Internet content.
The BlackBerry Internet Service uses the security of the wireless network that it connects to. Email messages that are sent between the BlackBerry
Internet Service and your BlackBerry device are not encrypted. However, email messages that are sent between the BlackBerry Internet Service
and your messaging server can be encrypted using SSL encryption. SSL encryption can also be used by the BlackBerry® Browser and other
applications on your BlackBerry device to help protect your data when you connect to the Internet (for example, while shopping and banking
online). You can also set up your BlackBerry device to help protect it from theft, viruses, and spyware.
I don't think it's fair for you to accuse without proper research.
