iOS

In honor of Major League Baseball's opening day (today! Go Giants!), Volvo has unlocked the paywall on streaming live games onto all iOS devices. For the entire month of April, all streaming MLB games will be free to view on MLB.tv.

Of course, to view the streaming content you'll have to be subjected to some Volvo ads, but for baseball fans it seems a small price to pay. It also guarantees a lot of eyes on your ads, which is something that may become more popular as more and more high-profile paywalls are announced.

Sadly, it's not completely free — to access the streaming content you need to pony up for the official MLB At Bat iPhone or iPad app, which is $15. Android users can get in on the action, too — you'll be able to watch one free app per day.

After a few rumored false starts yesterday, the iOS 4.3 update is now available to download on your iPhone, iPad, and iPod Touch via iTunes. We got an idea of what to expect in the update during last week's iPad 2 event, but in case you missed it, here's the rundown on what it's packing:

• Safari performance — The new Nitro JavaScript engine inside Safari will make it twice as fast and responsive as it was in 4.2.
• iTunes home sharing — Play your iTunes library from anywhere in your home with a shared WiFi connection. Play a movie from your PC on your iPad (or vice versa), or stream songs from your iPhone to your Mac computer.
• AirPlay — This update provides improvements including audio and video streaming from apps, allowing you to shoot video with your iPhone and instantly share on your HDTV.
• iPad side switch — Make the choice between a mute or screen rotation lock on the iPad side switch!
• Personal hotspot — This will allow you to share your WiFi and 3G connection with up to five other devices from your iPhone 4, each being password-protected and secure.

This is excellent news. According to an in-the-know source, Apple is planning to revamp its push notification system for iOS. Its current pop-up system has been criticized for being intrusive, ugly, and almost useless — dismissing the notification (to use another app or feature, for example), makes it easy to forget that the notification even existed.

We were pretty stoked to get a bunch of new features in the iOS 4.2 update a few months ago, but now it seems we have even more to look forward to with iOS 4.3. The developers' build was released to the building masses recently, and said developers have uncovered some interesting and exciting additions. Check out what they've found below!

Personal Hotspot
A big advantage to Verizon iPhone customers: the personal hotspot. While AT&T has said it is "still evaluating" the feature, developers have found a personal hotspot switch in the new iOS 4.3 build. Will it be coming to all iPhones with the update? Even more importantly: how much will it cost?

Find My Friends
Apple may be adding a Google Latitude-like feature to MobileMe, something called "Find My Friends."

Steve Jobs began today's Apple presentation by introducing the new features in iOS 4.1. This update comes with lots of new bug fixes but also allows HD video to be uploaded over WiFi, TV show rentals, a new game center, and HDR photos (high dynamic range), which bring your photos to life.

Good news for anyone who's worried about sensitive info on an iOS-enabled device; Apple recently submitted a patent application for technology that recognizes when an unauthorized user attempts to use any iOS device, locking that user out of the system and potentially even snapping their photo. The technology, which would be exceptionally helpful for iOS devices since they're meant to be mobile, would presumably keep data and devices safe should they fall into the wrong hands.
