There are lots of issues still apparent with the product. Allegedly hotfix 1 and 2 is contained within service pack 1. I am constantly noticing lots of different sporadic instances of problems with BES 4.0, the hideous hotfixes 1 and 2 and now the Service Pack. I have sent RIM a detailed description of all problems and they have conceded that most of the issues they have been able to replicate/know about. I'm now waiting for resolution.
