Thanks! this is very informative. :) Cash for cell phones available at cashforsmartphones.com
When I was looking for unlock code for my Samsung Corby Plus I found your blog,I tried the code you mentioned but it didn't work in my Corby Plus . So,I got the unlock code from TheUnlockSpot.com for small price and unlocked my phone. They also provide unlock Solution for many Samsung and other GSM mobiles.
