    I could reproduce this after like 2 seconds with 2.2.0 alpha but testing with the latest code I cannot reproduce this so looks like this may have been fixed.

    The latest code meaning the code for the next release. We don't give the latest code out publicly.

    We check in 2.2.1 and there is always the same problem.

    Someone has a workaround ?

    We are also seeing this issue on iPhone 4, 5, and iPads. The key for us to reproduce this easily and consistenly is scrolling top to bottom to top and especially it seems when you finger swipes over the top title/toolbar. This can be reproduced with 100% of the time, and we are using Touch 2.2.1.

    Hopefully this gets fixed soon as scrolling with lists is a fundamental and basic required feature that needs to be reliable.

    As an update for others, it seems that setting config option infinite: false may have worked around the issue for us.

    This is still not ideal because we have to be careful to limit the number of list items. Still hoping for a proper fix.
