Teardowns Detail Minor Differences Among Wi-Fi, GSM, and CDMA iPad 2 Models


iPad 2 antenna: GSM (top), CDMA (middle), and Wi-Fi (bottom)

iFixit announced that they completed the teardowns of the GSM and CDMA models of iPad 2. Wi-Fi version of the iPad 2 was torn down on launch day. The GSM model has the micro-SIM card slot along the upper left edge to provide the device with subscriber information. On the CDMA version such information stores directly on the WWAN board inside. The CDMA iPad offer slightly different antenna configurations, it has an additional antenna and an integrated GPS receiver. What’s really curious is that the 3G version of iPad 2 has the older Infineon 337Se833 baseband chip rather than a dual-mode Gobi chip found inside the CDMA iPad 2. Maybe it was a supply issue or an engineering decision designed to cut costs a bit.
