I have an iPhone 3gs as my main phone and I recently bought a blackberry tour with no plan. I think touchscreens are difficult to type with so I planned on just taking the SIM card out of my iPhone and putting it in the blackberry for messaging. The problem I'm running into is I'm not sure if the iPhones SIM card will work in the blackberry. Does anyone know if there will be a compatibility problem between the two?
