Runs on iOS 5 and the new A5 chip
Currently compatible with three wireless carriers: AT&T, Verizon and Sprint. The best pricing is contingent on a commitment to a 2 -year wireless service plan.
As with other smartphones, there is a “hot-spot” function, which can be turned on/off by request (no term commitment) available for $20/month. This turns the iPhone into a hub for WiFi or allows another device to connect to the phone via Bluetooth. Via WiFi, up to 5 devices can be connected to the phone at the same time.
