Hello.
I cant delete Voip services from E72. i made one mistake, when i tried to delete sip-profile: at first I delete it in net menu. After that when Im trying to delete it , phone return to me message: Service is in use. Cannot edit settings. That problem blocking hard reset, also (say something about active calls and connections, but Cell network and WiFi is inactive).
PS: Excuse me for my very very bad english.
