Can I unlock my krazr with no sim card port from metro pcs and make it compatible with cingular?

Question

(cingular needs a sim card)

Answer 1

Metro PCS uses CDMA network while Cingular uses GSM network so even if you could unlock your krzr you would not be able to use it on Cingular. Since information on the sim card would also be necessary that is another reason why you would not be able to.
