I have the iPhone 4 with the small micro sim on contract and I also have the BB 8900 unlocked, but I want to start using my BB now. I called up 02 and they said they can change my data plan for me on my next billing date but I don't want to wait that long, plus I need a new sim because the micro sim doesnt work on a BB.

If I go into 02 tomorrow and change my number into a new sim that will fit into my BB, and then call 02 asking for the data plan for the BB will I still have to wait until my next billing date or can they do that straight away?

Nothing will have changed, they will still need to wait until your next billing date.
Its the same account afterall.

The only things you can do is waiting....
