Nokia 60 Series :: Powerful New Virus Got Dc Within 20 Seconds?

A few hours back i got a phone call from my female freind who uses a Nokia 60 series. Only problem was She did not call! it was some creep who knew my name and got dc within 20 seconds.There is no record of the call in her mobile. but the service provider we both use logged teh 20 seconds call from her phone. When i told them that she had not made the call from her mobile and there was no such log on her phone. They refused to believe me and were adament that its not possible.After half an hour of useless arguments they simply refused to take my calls!When I called my freind and told her that some1 has been calling from her number without using her SIM. She also cannot believe its possible.Yet the call is logged on my phone n the service providers have also accepted it.I have heard bout viruses that send mass smses but this is the first time I have seen a phone number being used without its owner`s knowledge.More ever all the data on teh sim has also been apparently compromised.Since they knew my name as well.Now according to the service providers this is simply not possible and their system is secure.Is it possible that heckers can actuly take over a phone and gain access to all its data without the owner`s knowledge? I am extremely worried since the potential for crime and terrorism in my country is horrendously high. And with this kind of identity theft the number can be used for black mail extortion kidnapings for ransom even bomb blasts.. all of which are very common in Pakistan.
