I would send in a Contact Us ( possibly with the UDID from the iPhone). I am not sure if that will be enough, since you would have to find the equivalent on the Android. I am looking around trying to find a way to find that information out.
I've found that Android as an IMEI which I don't know if they GMs will be able to see this information as well.
Let me check up on this
I asked the GMs and they said right now there is no way to transfer between platforms. Hopefully, in the future, there will be a way, but as of right now, there is not.
