SIM not ready

[Sebastian Reinhardt]

I have some trouble with my GTA04. Since I updated to QtMoko v53 and 
receiving some messages (e-mail), the "busy symbol" (rotating clock) is 
shown on screen.
If I ty to delete some SMS, a message is shown, that SIM is not ready. 
Opening the system info -> SIM is showing the SIM ID shows "Please wait" 
on all positions (SMS used/free and Contacts used/free).
The SIM seems to be working (in other cellphone/ SonyEricsson P910i)! 
The phone is connecting to provider (is displayed in homescreen and also 
able to connect to internet/3G). Make calls is a little bit difficult. 
The call tone is there, but the called phone is not ringing! After hang 
up, the called one is ringing! Very misterious....GTA04 is not ringing, 
too (or later).
How to solve it?
