After editing and existing calendar entry when I want to view a contact the phone freezes up requiring turn off/on to get started again. On my 4th handset since 24th April (when Orange released the 650) and Orange not very helpful - exactly same problem on each handset. Also when adding or editing a new contact cannot access calander - again needs a restart. Tried hard reboot, problem still happens whether there is one calandar/contact on phone or it has been synchronised. Anyone got any ideas or similar things happening? - Otherwise I love the phone - Thanks
