emm, what "security code nonsense" with MfE are you talking about? Not being able to use a Mfe account withouthaving to input a code upon locking the device. This is is the only phone I have ever owned Where I had to do that. I consider that a nonsense. I don't remember why, but there was a decision to not support them at least for sales/PR1.1. No offence, but why not implement one of the main features of Exchange if you are going to support it? Not a SW developers decision, believe me Right now can change this setting only by using a hack . As far as I remember, now that hack become a bit more complicated because of some new aegis rules (because now you need to get a backup, change the accounts DB and then restore the backup on the device).
