Here’s the latest on iPhone OS 4.0. The beta 4 was only just released to developers and the data is pouring in about what’s in store for us post updates. The big news is for those who’ve been harping about the handset not having an option for internet tethering. Well when OS 4.0 hits iTunes for real, it will be possible for users to setup internet tethering on AT&T. However the hardworking testers down at Engadget were working hard getting the rest of the us the information, though they did seem to have a bit of hic-up in between.
