This week I've been looking at an 8300 as a possible upgrade. I was under the impression it was just the 8300 Curve, but looking on the Vodafone website (Vodafone Tariff details and call costs - Vodafone Mobile Phone Shop), I see they have it listed as the 8300 Prosumer. Is there any difference?

Thanks.

Your link didn't go to a relevant page, but no. A BB 8300 is a BB 8300. Curve is just the brand on the model number. There's only one.
