Still doubt that the 3G iPhone is coming soon?
This settings screen with a 3G toggle switch (see image) was found in the latest beta release of the iPhone’s 2.0 firmware.
Why would you want to turn off 3G? Because 3G drains cell phone batteries very quickly. In this screenshot, Apple has included a toggle setting to turn 3G off, and use AT&T’s slower but more battery friendly EDGE network instead. Probably a very useful feature if you are almost out of juice.
When can we expect to see a 3G iPhone and how much will it cost?
