I couldn't find any forum entry which could answer my question. I have rooted my Desire S. I do have the superuser rights. I did install rSAP V2.0.1 successfully but Afterwards I'm receiving the error massage:
SIM Status: rSAP Systemdateien nicht korrekt installiert.
I have deleted and reinstalled the app - no difference.
Any idea what I have missed
Thanks for your support.
