I have installed V7.45.1 as mentioned from America option for E90...etc etc.

Now can someone walk me through after that?

It gives me a message that enterprise activation is required and i should input email and password as provided by my IT admin. ( I need to use BIS and not BES)

Also in device details I don't have any PIN, which I require with the IMEI IMSI details to activate the BB service plan from my operator.

I am missing something or is my E51 crooked?
