Blackberry & Betfair

I started with a 8900 Curve which accepted Betfair mobile and it worked perfectly. I now have a 9300 Curve which will only accept Betfair Lite which I absolutely hate. I want to upgrade to a Blackberry Torch or Bold which accepts the full Betfair Mobile app. There are 2 x Torch and 2 x Bold. Does anyone know which would be the best for me?
