Need unlock code for Samsung SGH-E105

Hey i need an unlock code for a Samsung SGH-E105 that is run by T-mobile but i want it to run on any service mainly cincinnati bell. Well if you have a solution email me at slim_slim@tigerboard.net or add a post

if you had t-mo for at least 3 months they will give you the unlock over the phone

the phone is not activated through t-mobile its tmobile phone but i cant use it to call i have cincinnati bell and i like the phone for tmobile and i want to use that phone. I found codes a while back but it let me put any sim card in there but that is all it did i did not have service where i know that i had service with cin bell but if i would go to where tmobile had service the phone showed that i had service but still could not use it.
