Unfortunately, it can not load my iphone 4, no matter what I try. On the Internet I find no one with the same problem, so I just hope to a defect of the alarm clock. I will continue to report.
Addendum:
And only 5 minutes later I discovered the problem. One should not be so squeamish and the iPhone use caution but exert some pressure, then it goes again 1-2mm deeper into the connection and also loads.
