Unlock W550i Walkman

It worked! I ordered on Saturday and had the code on Monday. Followed directions and "NETWORK UNLOCKED."
I "almost" used another online company for this because it was much less in price, BUT after checking out some unhappy customer comments I decided to stick with this one since I know it worked on my other phone with no problem.
Buyer beware! Sure, the other cheaper one "may" have worked, but then "what if?" I wasn't going to take that chance.
