I'm switching to AT&T soon, but I can't pick a phone to get: an iPhone, or a Blackberry? My friends tell me to get the Blackberry, since I already have an iPod Touch and the iPhone would be "worthless." But I'm caught in the middle, because I hear that Blackberrys are more of a business phone, whereas the iPhone is for more personal-uses with all the applications. I'm 15, and I enjoy touchscreen phones and I think that the Blackberry keys would be too small for me, but I also hear that iPhones break easliy? Please give me opinions
