I got my new sony XPERIA arc S today. I added all the contacts I wanted and then decided to go onto facebook on my phone. When I went on facebook, it asked me if I wanted to sync my contacts to facebook and I (thinking 'all contacts' meant 'all contacts on my phone - not facebook') clicked 'all contacts.' Now, there is a substantial amount of, unneeded, names in my phone contact list and I am finding it extremely annoying to find the people i need to. I've tried to delete a contact by holding my finger on the name and/or pressing the button on the bottom left and pressing the delete icon but neither has worked. Please reply to this concern ASAP as I need this problem to be solved by the weekend. Regards.
