Most of my client are using blackberry and some of them own blackberry server, so it must be a stupid thing if I change to iPhone
iPhones are good if you want to jailbreak it and thus void your warranty. I owned a BlackBerry Curve and loved it, very customizable; Actually, completely customizable. I recently got rid of the curve and still didn't go iPhone, it requires too much commitment. A requirement to subscribe to media plans? I don't think so. I only need a media phone, which the blackberry did an excelent job of providing me. High quality video and audio with playlists.
