That link also contains messages from another system with an earlier kernel other iphone model and earlier iOS. What other information is required to get this problem resolved? Thanks J=C3=B6rg --=20 Joerg Mayer We are stuck with technology when what we really want is just stuff tha= t works. Some say that should read Microsoft instead of technology.
