I don't have an iPhone, yet I do have a BlackBerry for work. Whoever designed it must have had exceptional up-close vision and teeny fingers. My personal phone, on the other hand, is just a phone. I've had it since 2005 and it hasn't let me down. That said, I'm debating whether or not to get an iPhone just to have the features that didn't exist in 2005 (or 2010, for that matter!).
There are likely some videos on YouTube that can walk you through some of the initial steps.
