iOS 4.1 brought much-needed stability and performance improvements to the original release; iOS 4.2 brought iOS 4’s features to the iPad, which arguably needed them even more badly than other iOS devices; iOS 4.3 is polishes the original iOS 4 release to a dull sheen without changing anything fundamental to the experience.

For those of you with supported devices, there’s basically no reason not to download the iOS 4.3 update. You might not notice or use each and every one of its enhancements, but it’s certainly not going to break anything. This is just about as mature as iOS 4 is going to get - we may see the odd update to fix security or stability issues or possibly to bring the Verizon iPhone 4 into the fold, but this is likely the end of the line. If you don't like what you see in iOS 4, your best bet is to wait patiently for iOS 5, which we'll probably see more of later this spring.

    @Vadatajs:

    "Furthermore, Mac OS has always closed applications when you _quit_ them. "

    Yeah...exactly his point. An iOS app gets closed... when you _quit_ it. Individually. One at a time. Going out of your way to do so. Just like an OSX app.

    Point made. You just echoed it.

    So when I close a window it is supposed to do what is done in Windows (as in on the Windows machine on which I am typing this)? Sometimes it closes that window. Sometimes it closes multiple windows within a single window. Sometimes it closes multiple major windows -- even across multiple screens in a multi screen setup. Sometimes it closes (quits) the application. How doesTHAT makes sense?

    And MobiusStrip... how hard is it to do "Command-Q" for 99.99% of all applications? Seems much easier than to remember that for some applications it's Control-Q, for some it's Control-X, for some it's Control-E, for some there is no supported control sequence (just close every single open window and it quits the application). Yea, that makes much more sense!

    I am NOT saying Apple has done it the best way it (or anyone) possibly can, but knocking Apple's implementation when the way it quits things is the most consistent one out there is just stupid.

    why do you close them? they close automatically. what you see in the task switcher is only a list of what you recently used, not currently running apps.
  • solipsism - Saturday, March 12, 2011 - link

    WTF are you talking about? The Fast App Switcher when you double-click the Home Button? Those aren’t your running apps, those are a list of your apps as you’re last used them in the order you used them. You can test this by power cycling your IDevice and then seeing all those apps still in that list as soon as you can access the device. How the hell does one come to this site and not know that?

    I just installed it on my 3GS, and I noticed that in places in my apartment that I used to have poor service I have either full signal or almost full signal. I know they updated the baseband and carrier file, is anyone else seeing this?
  • MobiusStrip - Thursday, March 10, 2011 - link

    They're probably just dicking around with the signal-strength display again, to obscure the truth further.

    Remember when they claimed they'd been displaying it "wrong" for years? But when you actually looked at how they had been working, it was much more meaningful. It's a digital system, so for a wide range of signal strength, there's no change in performance. The meter used to reflect the variation across the significant (bottom) of the signal-strength range. But that was just a bit too much information for AT&T and Apple's comfort.

    It revealed the flaws in Apple's antenna design and AT&T's service.

    Actually the signal strengh issue was just the opposite as you describe as very clearly shown by this site in one of the most thorough reviews of the iPhone 4 anyone has done.
  • bplewis24 - Thursday, March 10, 2011 - link

    No, he is describing exactly what Apple did: they changed the way the battery signal was displayed and claimed they had been displaying it "wrong" for years.

    This site's review clearly illustrated the same, but it showed that the iPhone4 held it's signal at the lower attenutation better than it's predecessor did. It also, through a bit of subjective bias, tried to excuse it away by using anecdotal evidence (best case scenario by a person in a great coverage area) to dismiss claims that the problem was as bad as some thought.

    I understand why some features aren't introduced to older hardware, but they don't even give the new javascript engine? What the heck. Especially considering that last years 8GB Touch was second generation hardware, and now not supported. One year old hardware, not getting updates. One of the things I dislike about Apple.

    I was wondering if you could run your GLBenchmark 2.0 benchmark and see if there is any change in graphics performance in iOS 4.3?
