Well, I can help a little...
1. No, you cannot change the front screen saver. The stupid Cingular logo is stuck there until someone finds a way to get rid of it.
2. The Infrared is basicly just for when you have an Infrared piece connected to your computer and the software to sync it with your PC. A data cable would do the same thing.
3. The phone is always going to exit the menu if you keep it on there (I believe) and there is no way (that I know of) to change that.
4. To forward your calls to your home phone, just go into Settings, then go to Call Settings, and from there go to Call Forwarding. When you get there, select all voice calls, then select activate, and then to other number. From there, type in your home phone and hit OK. To deactivate it, go back to the All Voice Calls and hit Cancel.
5. No you cannot.
I hope this helps! And dont worry about the
cpf... I dont want it.
