Here my rant for the day- something I started noticing since I started flashing/activating/selling phones.
When cricket gets the eSN, if it is foreign, i think they put the model as a CPE "Customer Provided Equiptment."
I noticed that even if the phone i.e. (9900) is data capable, with the CPE model listing on the account, the data will not work. As soon as I go back into CID and change to say a Cricket V3, data works instantly.
