we have released a new update in AIO 5 SW firmware V32. This should work with many of the available simcards and has been tested to work better on iOS 8+ phones. More updates are available for testing in the test software if this one does not fit your needs but we thing is among the best releases yet anyway.
Also we are testing now V32 for AIO 4S (witch is an much improved V24 to be used on iOS 8+ and new and old simcards). This is also available now in the test software and we plan to release it in few days in the normal software.
You can post comments here about V32 for AIO 5 and we will try to help.
