I recently entered cingular contract and had SAMSUNG-D807 phone.I requested cingular to unlock it and they said no.I browsed internet and found many sites who do unlocking but charge around $29.99-$35.00.So I started checking further to find a reliable serivice and in that search I found this thread who gave clearly step by step instructions to unlock your D807.Thanks to him who spent time sharing his knowledge and experience and helping out people. Helping in this way might look silly for few but is a great relief when you could save few dollars. I would like to take the person if it is she to a dinner and if it is he for a game.

Thank you very very much and appreciate your effort....
