It’s a solemn act taken up after every update to webOS: reapplying all of your patches. While things have gotten to be significantly easier since the advent of Auto-Update Patch Technology (otherwise known as AUPT), there’s still some work that needs to be done. Or at least, some clarification.
So here’s the deal, as explained by WebOS Internals’ Rod Whitby: AUPT makes things easier for the end-user, but patience is still needed. As with webOS 1.3.5 and webOS 1.4, the version of webOS 1.4.1 that was pushed to users was different than the version distributed earlier to developers. While it’s not a major difference, the numerical difference is enough that the patches the WebOS Internals crew had prepped for release were no longer registered.
AUPT works like this: A log of your installed patches is stored on the device, when you perform a webOS update, Preware then references that log and redownloads the patches. If a patch hasn’t yet been ported to the new webOS version, then a dummy placeholder patch is downloaded merely to stand in place for when the update is made available. When the different version of webOS 1.4.1 was shipped and users attempted to reapply patches before they had been reverified, they simply downloaded a bunch of placeholders. A word of advice: don’t panic and doctor your phone the next time webOS is updated and none of your patches work. It takes time for the patches to be checked against the new version, and even then your favorite patch may end up broken.
