I can't activate my phone on the BES. I had some other issues initially, but I've figured them out except for this one. Options > Advanced > Enterprise Activation says "Not Activated". When I first got it, I went through the activation process and entered my username and password and the activation proecess started (and took a long time). The message I get is "The Server is not Responding". I received this email from the network: This message is used to carry data between the BlackBerry handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.
