Go Back and Forth Fast in Preview

If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.

The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).

 
 

iOS 4.3.1 Fixes Activation, Display, and Authentication Bugs

Send Article to a Friend

iOS 4.3 had been out for only 16 days, but that was enough time for Apple to identify a number of troublesome bugs and fix them in a quick update to iOS 4.3.1 for all iOS devices compatible with iOS 4.3.

Most notably, and this was undoubtedly the reason for the quick release, iOS 4.3.1 resolves bugs related to activating and connecting to some cellular networks. Given these bugs and the date of iOS 4.3.1’s release, it’s possible that it was scheduled to coincide with the international release of the iPad 2.

In addition, iOS 4.3.1 fixes an occasional graphics glitch on the fourth-generation iPod touch, resolves image flicker when using the Apple Digital AV Adapter with some TVs, and solves a problem with authenticating with some enterprise Web services.

As with iOS 4.3, 4.3.1 is compatible with the iPad and iPad 2, the iPhone 3GS and GSM iPhone 4 (not the Verizon Wireless iPhone 4), and the third- and fourth-generation iPod touch. The update is available only via iTunes; download sizes are in the 500 to 600 MB range, so schedule some time for it if you don’t have a high-speed Internet connection.

Unfortunately 431doesnt fix the battery issue on my iPod. It drains about twice as fast as it should
Am I the only person still pining for the days of iOS 3.x, when the iPad just worked? Now it has multitasking, which I guess is good, but it crashes more often than my Mac.

As Matt Neuburg has written, dealing with multitasking in iOS 4 is non-trivial, and I suspect a lot of developers aren't doing it right. In other words, I suspect it's not the iPad that's crashing, but particular apps.

Why do I read on every Apple/iPhone/iPad page someone placing the blame on developers rather than Apple just implementing a feature badly?

Multi-tasking on the iPhone/iPad is poor with the solution not really multi-tasking (playing itunes in the background is not multi-tasking, just basic functionality that phones had years ago).

I'm a PC guy who loves Apple. I have been tempted to get an Andriod phone but because of how Apple keeps the iOS updated,I am not. That's the beauty of Apple,Update and Fix and keep it current.
