iphone 4 PPS activation experience

I asked for advices of activating iphone 4 on PPS some time ago.

Here is my experience.

I have a phone that is already using PPS, just want to change the phone and keep the number.

1. Get iphone 4 16gb Verizon from ebay at $75.
2. go to PPS online chat.
3. Give them the  Iphone's Meid/ESN number and the phone number and ask to port the old number.
4. Give them the old phone's ESN/MEID number.
5. End chatting
6. Get on the wifi, working beautifully.

Note: The online chat told me to do *22890 *228.., I couldn't figure out how to, but once I was on wifi, everything works.
