Over the weekend some folks digging in the latest iPhone 3.0 beta 2 firmware build discovered some references to the possible wifi chip for the next generation iPhone due in June. The chip reference is the letter/number code BCM4329 which can be assumes to be in reference to a chip manufactured by Broadcom.
Obvious features of this new chip include 802.11n support to handle those new speedy 5 GHz wifi networks that the iPhone 3g doesn't support. While faster internet on the phone is all well and good, 9 to 5 Mac noticed some interesting details while digging into more specs about the chip.
