Can I use the the Cingular SGH-d307 with Cricket Wireless?

I have a Samsung SGH-d307 originally a Cingular phone before At&t took over and I wanted to know if I can unlock it and use it with Cricket Wireless.

Hi if you want to unlock your Samsung SGH-D307 mobile from cingular network .Then visit Superunlockcodes.com here they ask you the IMEI number of your mobile .Then at last they deliver you code to unlock your mobile.I have no idea about whether unlocked GSM phone will Accept CDMA sim in it because Cricket is cdma .
