You only need to set up email accounts on the T-Mobile web site if you're going to use BIS -- either in addition to or in place of BES. If you're using it with BES, it really doesn't matter which order you use to set them up.
you are right to an extent i had this same problem when i attemtpted to do enterprise activation the icon disapeared on me.... YOU DONT NEED TO WIPE YOUR HANDHELD TO FIND IT AGAIN
go to settings and then scroll down to your service books select that andthen scroll down to where it says PROVISIONING and highlight that.....then hold the alt key and press delete and it will delete that and your Enterprise Activation button reappears at the home screen..
