Mobile broadband and Apple Snow Leopard

clock September 4, 2009 11:41 by author christer

Live from Twitter on this subject:

There's been reported severe issues and incompatibilities when trying to use mobile broadband connection software with the new version of Apples operating system for Mac called Snow Leopard.

The error occurring is a hard (kernel) crash of the Apple Mac operating system. In other words, access to Internet using mobile broadband is impossible. The Mac system itself survives, and there are no reports of data loss. 

I have very little information so far, but affected connection clients reported until now are from Telenor (Sweden), 3 (Three) (UK) and O2 (UK).

I'm working on getting more info. Are you affected? Please let us know more in a comment below, and please provide:

* What you experience
* Mobile Broadband provider name (such as Three or Telenor)
* Country
* Operating system
* Computer type

[Update] Vodafone (UK) has problems as well.

[Update no. 2] Virgin (UK) also has problems.



Fix for image compression on O2 mobile broadband

clock August 16, 2009 18:26 by author christer

If you’re a O2 customer using Firefox to browse the Internet there’s a fix for the O2 image compression they force upon your on their mobile broadband. You can perform the follow configuration of Firefox to get normal images:

1. Install Modify Headers add on.
2. On the Modify Headers screen add the following new names and values:
NAME:Pragma VALUE:no-cache
NAME:Cache-Control VALUE:no-cache
3. Click on the configuration button and select the always on option.

Original forum thread. Thanks to @asimoa for providing this fix.

This, unfortunately, only improves your viewing experience in Firefox. Images in other applications are still in poor quality.

[Update] Fix for O2 iPhones.

O2 delivers Internet via mobile broadband – but what Internet?

Apparently it’s a highly compressed one. Yes, O2 (UK) gives you a compressed Internet browsing experience by compressing all the pictures you download from web pages before they get sent to your computer.

I’d heard rumors about this before. But a few days ago I came in contact with a mobile broadband user on twitter, who could not only tell me how it affects you as a user but also provide a screen shot.

Below is a example of such an Internet experience. If you click the image, you’ll get it in the original size. As you can see, the images on the page are highly compressed and compression artifacts are clearly seen.

You can argue that this is a good thing because you then get more from you download allowance, sure. But you could also argue that this is a strategy chosen by O2 to get as many users on their network.

The problem is, however, that potential customers are not told about this aggressive compression service(?) before they buy their product. O2 customer are simply not getting the same Internet as the rest of us, and that they’ll not know until they buy the product. That’s just #evil business.

And it doesn’t stop with your web browsing experience. Images in other Internet connected applications are affected as well. The aforementioned user could confirm that images in for example iTunes are compressed aggressively as well. And that there’s no way to turn it off, as this compression happens before the images even reaches you computer.

[Update] See fix here.

I love mobile broadband!

I am an independent mobile broadband enthusiast. I find the mobile broadband business and related products very interesting, especially in the perspective of how usage of mobile broadband will change our work life and our social life

SPECIAL FEATURES: If you're a 3 user you should definitely read my blog post about 3Connects excessive logging that slows your computer down and what you can do to remove it. The O2 image compression is covered. Latest is the Apple Snow Leopard incompatibility with mobile broadband connetion clients. It's all here in this blog. And of course, there are plenty of other mobile broadband posts are available as well.

When not blogging about mobile broadband I work as a software developer and architect. You'll find my personal blog here: http://www.christer.dk/
