The 3G-capable iPad's launch on Friday has brought about several discoveries in the past few hours, including dissections of its hardware and word of long lineups. A teardown by iFixit has revealed that the cellular-ready Apple tablet has a dedicated communications mini board that houses all the 3G equipment separately from the main design. It uses the same Infineon X-Gold PMB 8878 chipset as the iPhone 3GS, but it has switched from Infineon's Hammerhead II GPS chipset to a single-chip Broadcom BCM4750UBG that provides assisted GPS.
