A quickie in case anyone knows, and didn't think this was appropriate for the other forums. I had an Orange iPhone 3GS and a few months back really needed some cash for fixing my bike, so I sold it. Put the sim (contract) in an old Samsung i600. It works fine. But i'm wasting my data plan on a phone that does internet, badly.

If I get an Orange , Blackberry 8520, can I use the iPhone sim in it with the data plan (unlimited data) etc ? Does anyone know, or do they use special BB sims ?

You can use the ordinary SIM, but in order to use Blackberry email, messenger etc you'll need to add Blackberry Internet Service to your contract. I'm not sure what it costs on Orange, but T-Mobile charge me £5pm for mine.

Thanks for that info.
