8PROS: great high quality phone
CONS: greedy service provider
If you're reading this more than likely you either have the E815 or you want to get one.
The E815 out of the box is a wonderfull phone. Reception and battery life is steller. Even if you only use the phone for making calls and could care less about the other features, this is still the phone to get.
Its unfortunate but the phone is heavily locked down. I plan on enabling the majority of the feature set.
This is a feature that I won't use much but it is easy to turn on. Dial ##DIALUP quickly into the phone. If done correctly you will get a message saying the dialup networking is turned on. Dial it again to turn it off.
I am going to point you to the links that will get you going.

Please note that the guide says you don't need PST anymore. You can enter a code on your phone to do what the program does. This didn't work for me. Use PST. I did my seem edits using windows 2000.
