Since the iPhone OS 3.0 Beta software was launched a few weeks back, it has given plenty of time for people to take it apart and look what’s in the code. Some interesting things about wi-fi connectivity were found which indicates a faster wi-fi connection.
Some wireless radio details are found within the beta software which indicate a newer Broadcom chip numbered the BCM4329. This chip is an upgrade to the older phones which use the BCM4325. The BCM4329 (new chip) as well as having wireless networking dual-band (2.4 GHz and 5 GHz) 802.11a/b/g/n it also has Bluetooth 2.1 EDR and an FM receiver/transmitter. It is unknown so early if the iPhone will make use of all these features but no doubt wifi and Bluetooth are an essential and definite.
If using the iPhone on the 5GHz network frequency there is also less chance of interference from other external devices which will further speed up the signal. With not loosing signal as much this would help power efficiency helping the battery last longer too.
If any more gems are found in the iPhone OS 3.0 code we will be sure to let you know.
