FCC filings show iPad Wi-Fi + 3G is larger

In addition to the disclosure in Apple’s just-published FCC filings for the iPad that there are two Wi-Fi antennas per model, a separate Apple document has disclosed a previously unknown difference in the dimensions of the Wi-Fi and Wi-Fi + 3G models. According to the document, the Wi-Fi + 3G model is 0.3mm taller and 0.1mm wider than the Wi-Fi only model, in part apparently due to the 3G model’s top antenna panel. This is in addition to a previously disclosed 0.1 pound difference in weight between the models, which was announced on the date of the iPad’s introduction in January. Though this difference in dimensions is very modest, it will likely impact the compatibility of individual iPad models with some precision-molded cases and other accessories, which are commonly manufactured to fit tightly on Apple’s devices.
