I received the iPod Touch 3rd Generation device I bought off eBay today, and when I tried to run LMC 3D, it crashed shortly after starting my app.
I have just tested the previous version of my app v1.1.0, and it works fine on the device. Therefore something I added in the latest version v1.2.0 is causing the problem on the iPod Touch 3rd Generation device.
I think I have a good idea what may be the cause of the issue, I will carry out some further testing, will post another update tomorrow.
Thanks for patience whilst I fix this issue.
