Sprint vs. Verizon moving from TP to TP2

[TTBadDog]

I work for a two letter computer company ending in P. We have a choice of "corporate approved" phones that I can use. We probably buy thousands of these and our IT dept does not want to support 20 different kinds of phones with security MMS, etc.
I would much rather get different phone even if I paid for it myself but they would spot on our intranet and shut it down.
