Apple hosted its latest event last night, taking the opportunity to tweak the iPhone a little bit more with the launch of iOS 4.1.As the name suggests, it's not a major update, but it is significant, with new features thrown in. First up is HDR (High Dynamic Range) photos, taking three snaps at once, one over exposed, one under exposed one and a normal shot. The three are combined, with you having the option to pick the best.There's now also HD Video uploading, essentially allowing you to automatically upload your high-def mini masterpieces and a new Game Center, now offering multiplayer gaming options including the ability to challenge friends, keep track of scores, and new ways to find games. On top of that, a few bugs will also be ironed out, relating to Bluetooth, proximity sensors and the interface on the iPhone 3G. All of it is free via iTunes next week.Talking of iTunes, an update to iTunes 10 was also announced. Most notably, this now includes Ping, Apple's take on a social network focusing on music, allowing you to follow people (including bands), establish a network of friends, post comments, check out custom song and album charts and find over 17,000 concert listings. It will also be heading to the iPhone as well, offered as a free download via iTunes when you upgrade to iTunes 10 - just as long as you have iOS4 running on your handset. iTunes 10 is available to download now.
