SyllogismCheck, too late for you I suspect, but if you go to the "Calls" list (where you'd expect to see the numbers you'd recently called and those that had called you) you will find an option titled "Notepad". On there you'll find the last number you keyed in.
I've had lots of phones and the only time I've gone from one model to an upgraded version of the same thing is with a V3 (and then V3i), so I guess I must like it. One nice thing that it does is allows you to dial hands free by just saying the number or the name from your phonebook without having to train it for each one.
