So you don't have a couple of gift cards and an AT&T rebate check to help take the sting out of the $199 price of an iPhone? Or perhaps you don't think you will use a mobile device enough to justify the purchase of the product as well as the data plan. Despite what Apple, Blackberry, and the fine folks at the cellular companies think, not everybody needs a smart phone. But how do you know what resources are available and how do you test them and the phones if you don't have a smart phone? Never fear, the Pacific Northwest Regional Medical Library blog, Dragonfly, has an informative post, Tiny Little Screens, that offers information on some information resources for/on handhelds and lists some simulator sites for the iPhone, BlackBerry, and Palm where you can test and see how things display and function.
