Apple Releases iOS 4.1

| Product News

Apple released iOS 4.1 on Wednesday for the iPhone and iPod touch. The update includes several new features such as Game Center, HDR photo capture, HD video upload support and TV show rental support.

iOS 4.1 also fixes several security issues including a flaw that could let an attacker redirect FaceTime calls with a maliciously crafted certificate, and a flaw where maliciously crafted TIFF or GIF images could be used to crash apps or run arbitrary code. WebKit for iOS received its fair share of security patches related to maliciously crafted SVG files, the handling of text nodes and element focus, fonts, HTTP redirect handling, CSS encounters, JavaScript arrays, and more.

The update is compatible with the iPhone 3G, iPhone 3GS and iPhone 4, as well as every iPod touch after the first generation model. Not all iOS 4.1 features, however, are compatible with every device.

iTunes iOS 4.1 update dialog

To download and install the update, launch iTunes on your Mac or Windows PC and connect your iPhone or iPod touch. If an update dialog doesn’t appear, select your iPhone or iPod from the Library list, select the Summary tab, and click Check for Update.

Some users are reporting on-again-off-again availability of the update, so you may have to try more than once to get the update to show up in iTunes.

To learn more about what iOS 4.1 includes, check out our iOS 4.1: What You Need to Know article, and our iOS 4.1 upgrade guide shows you what to do before and after installing the update.

iOS 4.1 is a free update for iPhone and iPod touch users, and weighs in at 589 MB. iOS 4.2 will be available in November and will include iPad support.

No update yet here in the Philippines.


Got it! Put it on my 3G. FINALLY I can use my iPhone with pride again. All the slowness and crashes seem to be eliminated with this update.

So why don’t I have an iPhone 4 yet? Well I’ve been trying. I dropped the 3G in a creek in June, just in time to get a 4…. dried out and has no problems. So this weekend I ran over it with my tractor…. the CaseMate skin is destroyed but my iPhone continues to live on. :-( 

Let’s see…. maybe a shooting accident….


I walked into the sea in Sarasota, Florida. Had the phone on my shorts. Saltwater killed it….

I just finished installing iOS 4.1, and all appears well.
My 3GS had a nasty bug that I had not heard of before, and I was able to repeat it with TWO replacement phones.

Here’s the post describing it:
iPhone 3GS Locking up After Low Battery Shutdown Bug

Fingers crossed. . .


Does anyone’s apps start getting laggy after opening and

Seems like the iPhone 4 starts bogging down after opening camera and photos. Anyone else notice this?


It’s working really well on the 3G I have. No more lag issues, apps loading as they should again, definitely an improvement all around speed wise.

I have not done any scientific tests, but my 3G seems to be faster than it was under 4.0 and maybe as fast as it was under 3.0. I will try and to do some speed tests comparing my wife’s 3G which was not “upgraded” to 4.0


Was not released when I went to bed circa midnight Dhaka standard (where I am now). Installed this AM, without a hitch.

The calendar is once again responsive, was bleeding slow on iOS 4.0 (granted, mine is chockablock full, but very fast on the iPad), but now is once again snappy and useful on my 3GS. No other appreciable differences on this device.

Looking forward to upgrading to an iPhone 4 in a few months (I know, I could stop being a cheapskate and just get one as soon as I get back from the field).

I compared my 3G running 4.1 with my wife’s 3G running 3.1.3 and I can find no appreciable difference in speed. Sometimes an app would load faster on phone or the other, but just a fraction of second and it is possible that the difference in my timing of the event.

So far I am happy with this update. However, I don’t know at this time if I will upgrade her iPhone to 4.1 or not, maybe wait a few days.


I compared my 3G running 4.1 with my wife?s 3G running 3.1.3

Many thanks, Sir Harry. Will now recommend my wife update her 3G to 4.1.
