Mine came Saturday morning USPS and so far it's been great... integration with Exchange Server is flawless. Good luck calling Nextel, tho... they're still trying to figure out how to make the phone work.
I have found one issue... the phone is Application Locked - which means software non approved by Microsoft is blocked from installing. I purchased imov Messenger to use AIM on the phone, and the install fails. "Installation failed. The program or setting cannot be installed because it does not have the adequate system permissions."
imov doesn't know how to fix it, I spent over an hour talking to Nextel support people and they can't fix it (or even understand it)...
This lock looks like something that has been hacked on other Smartphones in the past...
Any ideas?
