You don't need to have the device activated in order to unlock it. You will need the IMEI number which can be obtained from the first page of the activation screen. If you turn the device off, then back on, on the first screen (the one with the "Hola!, Hello! etc) there is a little circle with an "i" inside, down in the bottom right corner. If you tap that icon, it will give you the IMEI number.
Once you have that number, submit it to one of the online iPhone unlock services. Once you have been notified that the iPhone is unlocked, insert any sim card into the device. You will then be able to complete the rest of the activation process and you will have a fully unlocked iPhone.
Hope that helps,
