What to ask before signing the contract.

I found that if I port my phone number to sprint that I can get a $100 credit.
[FONT=&quot]o [/FONT]Is it still active?
[FONT=&quot]o [/FONT]Does anyone have any experience with this?
[FONT=&quot]o [/FONT]Would it be honored at Best Buy, Walmart, Radio Shack or Sprint Store?
[FONT=&quot]o [/FONT]Is it per phone number ported or per plan?
