Blackberry Pearl (8100) - Reindexing contacts for voice dialling

I've just got a new Blackberry phone, to replace a handset I lost on my last holiday. Some of the guys I used to work with at E3 have been on about how it's the best mobile they've ever used.

So far it's been very impressive, particularly the blackberry email system. Emails just appear on your phone, no send and recieve or constant checking. They use a push system which is very smart. Anyway the only problem I've had so far is that the voice dialling didn't recognise any of my contacts. It seems like when it indexed the contacts the first time it didn't work and since then it only reindexes a contact when you edit them. The fix was on this page, basically wipe the contacts by syncing them with something other than your primary contact list, in my case I stopped syncing them with Outlook, instead syncing them with Outlook express, which has no contacts, doing a complete export replacing all the contacts on the handset. I then set it back to Outlook and did the same and then finally set it back to sync rather than export from outlook.

Next time I went to use voice dialling it reindexed my contacts and this time it all worked fine.
