I receive a lot of calls on my mobile, 0800 numbers diverted to it.  Im having a problem where the phone just randomly pics a contact and replaces that contacts number with a number from the recent call lists.  I have lost some of my numbers as a result.  And to top things off I just went to call a friend from my contacts and got a surprise when a customer of mine answered instead! Closer inspection revealed the phone number under the my friends contact entry had been changed to the phone number of a customer I had recently been dealing with and had called a few days ago.  I don't usually save customers numbers unless they are regulars and this customer was definitely not a regular.

Now I need to know if anyone else is having problems like this?  I have sifted through Google and not found a thing relating to this.

It seems to happen just randomly, possibly once every couple weeks and I just cant work out why?  But its very frustrating, I now have to check each contact before I call them to make sure their number is correct.  Im just ready to throw this piece of crp out and go back to the green screen 6 year old nokia I was using which I never had problems with.
