Apple is set to launch iOS 4.1 for iPhone and iPod touch users this week. But a developer preview has been available for a little while already, and it turns out the latest build installs just fine on pretty much any supported Apple mobile device — even if you haven’t ponied up the $99 for a developer license.
The folks at Uneasy Silence tracked down the files you need to install the update on the iPod touch 2G or 3G or an iPhone 3G, 3GS, or iPhone 4.
Bear in mind, Apple will be pushing out the official update in a few days, so if you want to stay on the up and up you might want to wait just a little longer. On the other hand, if you simply can’t wait another day to find out if iOS 4.1 really will improve performance on your old iPhone 3G, now there’s an option for the impatient.
