Wi-Fi Sync recently reached the 20,000 sales milestone; huge thanks to everyone who has purchased the app. This is a fantastic achievement for the iPhone jailbreak scene.

Work on Wi-Fi Sync 2.0 is progressing well. The new release will fix the outstanding issues reported by a small number of users, in addition to some new features such as sync-over-3G support. You’ll also be able to disable automatic backups for wirelessly connected devices only, rather than disabling backups for all devices (even those connected via USB) as with the current version. 2.0 will also be far friendlier to those who like to manage their own startup items; you’ll be able to start and exit Wi-Fi Sync whenever you like, and you can choose whether to run it at startup. I don’t even plan to ship an installer - instead you’ll be able to copy the app into Applications, like many other Mac apps. It will require iTunes 10. I’ll have more news shortly.

When I started work on what would eventually become Wi-Fi Sync, I couldn’t have predicted the fantastic success that it’s enjoyed over the last week. The app has already sold 3,000 copies, and articles have appeared on Engadget, TechCrunch, BBC News, BBC Radio, Gizmodo, Wired and many foreign language blogs. Thanks to everyone who has sent suggestions, comments and feedback.

I’ve had a lot of questions about iPad and Windows support. I think I’ve had a breakthrough with the iPad (largely thanks to comex, author of the Spirit jailbreak), so expect more news on that very soon.

I’ve just come across these Microsoft-provided Virtual PC hard disk images for testing sites in legacy versions of IE. If you’ve ever suffered the hell of trying to install and maintain different versions of IE using registry hacks or 3rd party solutions, you’ll be relieved to hear there’s now a better (and free) option.

Images of XP SP3 and Vista are available. They’re currently set to expire on 01/01/2010.

If you use MAMP for local PHP development and try to access the ZipArchive class, you might find yourself on the receiving end of an error message similar to this one:

Class ‘ZipArchive’ not found in /home/…

MAMP doesn’t come with PHP’s zip extension, so you either have to compile it yourself or drop a precompiled copy into your extensions directory. Compiling is a pain and precompiled extensions are hard to come by, so to save time, download it here and copy to /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20050922. (Update: Link no longer available.)

Don’t forget to enable it within php.ini. You’ll also need to make the downloaded file executable: chmod +x zip.so

Upon attempting to install Silverlight 3.0 on my ‘hackintoshed’ Dell Mini 10v, I found that it wouldn’t play ball due to an incompatibility with PowerPC (despite the fact that the machine uses an Intel processor).

I’ve modified the installer so it skips the CPU check, and will thus install on PPC-based Macs and OSx86 machines. You can download it here: Silverlight.3.0.pkg. (Update: Link no longer available.)
