First problem was, that after I have read an SMS the red 1 disappeared, everything fine, but after a restart of the iPhone the red 1 was there again and the SMS marked as unread.
Okay, don't care, but my next problem:
I can't send SMS. Even if I want to send, the bar stops close at the end while there is written "sending" and nothing happens.
I can receive SMS.
SMSD is crashing when I want to start it, reinstall doesnt help.
Sorry for my English ;)
