"Free" Wireless Service

I took the Singapore Airline flight to Singapore this time and the plane landed and took off at the Terminal 3 of the Changi Airport.

I learned that the T3 is brand new and it was opened on Jan 9.

On the return leg, I asked and found that there is free wireless interest service available. So I tried and found that it requires registration. Of course, I followed which required me to give up my phone # and email address. However, when I got the confirmation note, it requires me to check my email to get the password... but without the password I cannot use the Internet to check my mailbox... so what's the point?

I thought something like this will only happen in, but Singapore?!?!?!
