After seeing repeated requests for Sprint Employee E-Mail Addresses and the Last 3 Digits of the Employee's ID Number (CID) to get Sprint's Simply Everything Plus Plans (which replaced SERO), here is an employee's information that was intentionally made public: (Reference: McGuire’s Law Blog Archive Psst - Have you Heard about Everything Plus?.) This information was made public by Russ Mcguire on 7/16/08
UPDATE: As of 2/15/09, Sprint has added a family plan version called "Everything Plus Family". You can access it using the same link/e-mail/CID as in the original post. There is also an "Exclusive Referral for Mobile Broadband Cards" plan as well (although this has been there a while now).
