FYI update we have been able to modified our free iBird Lite so that you can upgrade it to any of our country databases. If you have purchased iBird Plus or iBird Ultimate and they are on your device, iBird Lite will recognize them and the North American database will be free to download. From then on we will continue to update iBird Lite and its databases and you will not have to pay for it. I apologize for how long its taken us to get this working but it's been very difficult to get all the pieces working together. We hope to launch in the next week, baring any last minute glitches, so I can't guarantee this right now.
We will also be updating iBird Plus, Pro and Ultimate so they will have the latest databases and IAP features, so that you can continue to use them. But per Apple's rules Plus and Ultimate will be frozen and not updated in the future. Again iBird Lite will be your solution to free updates in the future. You'll even be able to change its icon.
Thanks for your understanding and patience.
