RIM security is good BUT it needs/uses servers
RIM security has always been good, ask Obama, BUT it's weakness is it's use of servers which can be used to obtain / access decrypted messages. And, of course, Plod, RCMP, FBI, et al, are able, and do, access this information. With distributed, corporate, servers, corporations might satisfy their needs for access.
These days Silent Circle provides a good solution - the 'encryption', in effect, is in your hand. Whilst I am not in the habit of building UIDs or remote triggering devices, my communications are mine, and simply none of the business of any government or civil servant.
An added feature with Silent Circle is the new ability to send files of up to 60Mb fully encrypted which should satisfy most users.
Notwithstanding this limitation, BB has always offered a quality product and let's hope they return to their former glory. Unfortunately, I will not be a user as I am happy with my Samsung Note 2.
