Just created a test in new release of PTP2 with KRPano 1.17. The image quality is incredible on mobile devices. I just have one question regarding the iphone 4. I tested the tour on iphone 4 & ipad 2, would there be any way to increase the auto rotation speed just on the iphone 4 version, it's fine on the ipad 2 and on a PC but the auto rotation seems slow on the iphone. Have a look and see what you guys think.
