Honestly on a CDMA network i can almost find it impossible to unlock a Sprint phone and use it on Verizon,i use to work for Sprint Corporate 2 months ago, i now work for ATT, i am pretty knowledgable at this, i probably am wrong but due to my expirience i cannot see how this would work. The ESN needs to be registered on the network in order to use your phone. What the MSL does it allows you to access the program information, the PTN and MSID on your device the MSID is the most important part of the programming of a device. To make it simple to what i understand the MSID lets the phone know how to connect to the network, in order for the network to allow your device to make a phone call the ESN has to match with the ESN registered in the account, the billing system will not allow you to register an ESN that is not for that particular provider because the serial number is not recieved on their network inventory, the billing system wont know what kind of device it is. It all depends on the provider if they let you register the ESN in the network and set a default Compatibility of the device such as the device being a 2G or 3G in order to let the billing system provide either 2g service or 3g. Most major carriers like verizon and sprint will not let a device from another carrier to activate on their network.
