You don't need a static IP for the phone in order to connect to your desktop.
You just need your house's IP (preferably use dynamic ip), your login name and password.
In XP you just right click on my computer, goto properties > remote > and check "allow users to connect remotely to this computer"
Then open up remote connect, type in your house's IP, login name and password and that's it.
If you're using a router this gets more difficult as you have to log in to your router and allow port forwarding of port 3636 I believe it is, but if you have a router, go online and search for any RD tutorial as I said before, and you can very easily get this set up. If someone's having trouble, PM me and I'll see if I can help, don't post any more about this in here
Can you post new kitchen along with the rom... pretty please!
