Issues with MSN and Rogers Blackberry

Hi all, I have a good friend who is on the Rogers network with a Blackberry Bold 9700. Frequently, but not always, MSN will dump with the following error: "There is a problem with the server. Please try again later.(100)". The 'net is littered with these complaints, and it appears to only affect Verizon/Rogers networks. Does anyone know of a workaround, or are there any Rogers/MSN engineers who can contact me off list to try to figure it out? Thanks, Steve
