If you have purchased the Basic version of Boldbeast Recorder and want to upgrade to the Advanced version, please send 19.99 - 14.99 = 5 USD to us with PayPal, then we'll send the advanced register code to you for the same phone (the IMEI must be the same as the Basic version).
Our PayPal account is service@boldbeast.com.

I already have the advanced version, but I wonder if it would be possible to get the version C2M paying the difference.
