C600 Autocomplete on Call Fowarding

[Guest El_Tel]

Rather than lug two phones around, I often forward calls from my own mobile phone (C600) to my business mobile. Unlike my trusty old C500, I have found that the C600 doesn't seem to autocomplete phone numbers that are typed into the call forwarding number field (that have been entered before). I have to enter them in their entirety each time. Call me lazy or forgetful (I can never be bothered to memorise my company mobile number) but I find this a real pain.

Do I need to turn autocomplete on? If so, how? Or is this another case of two steps forward and one backwards with WM5? Thanks for any help you can give.
