I did it over the weekend and works fine.

ok thanks.

it says at the end the "iworld" may not work.

Will this work fine on Tmobile UK ? sending/receiving calls/sms?

Thanks in advance,

I followed these steps but I get a message at the end "anySIM can't unlock this phone"

I followed that guide,and got the same message.I suppose your trying to unlock on 1.1.1 FW - 4.01.13_G Modem. Just upgrade to 1.1.2 4.02.13_G, then use anySIM 1.2.1u on airplane mode.It should work.
