OK, this is a rather noob sounding question, so no flaming please. I had one of the original iPhones, and had been relegated to the world of Blackberry after only 6 months. That sentence is coming to an end. I have been using a 3rd party exchange host (Mailstreet) and it has been working great. When (not if) I switch back to the iPhone, is there any solution as efficient as the exchange I am used to? Or, do I just continue with the Mailstreet service. The wireless syncing between my iPad, iPod Touch, desktop (Outlook for Mac2011) and future-former Blackberry have been seamless. I don't want to loose that. Is there a definitive blog regarding this type of stuff?
