A 14-year-old modder has apparently managed to replace his Apple Watch’s bubbly default home screen with something a little boxier and more classic: iOS 4.2.1, which launched all the way back in 2010.

Billy Ellis, a self-described “iOS app and tweak developer,” posted a video of his project on YouTube. Check it out below:

Solve iPad Low Memory Warnings on iOS 4.2.1 [How To]



Apple’s iPad is the first generation of what I hope will be a long line of magical tablets. Unfortunately,  it has one minor problem that will be more evident now that iOS 4.2.1 has been released.

That problem will be the made evident by the over zealous use of multitasking on a device that only has 256MB of memory in which to run applications. The iPhone 4 twice that or 512MB.  Users won’t be able to help themselves because multitasking is just to valuable to ignore or give up.

So the problem of having less memory to run apps will be frequent warnings that “your device is running low on memory. ” I’ve seen it happen to others and the image above is my own personal encounter with the problem. Apple had given the iPhone 4 pretty liberal amounts of application RAM, so I was  a bit taken aback that the iPad didn’t have at least 512MB to 1GB of RAM when it was released.

Fortunately, the work around is easy.
