I think a bunch of you were asking for "blackberry-like" service from the 7135 where you can receive your exchange mail and appointments and respond to them, and responses appear from your exchange account. There's a local company here in Vancouver called Infowave that has an interesting service. It's not always on obviously but it does provide the ability to send as your exchange account and accept meeting requests etc. I haven't tried it since I'll never purchase it but I thought you corporate users might be interested.
