iOS 6.1 was released yesterday, and it brought a few new features and bug fixes. The lockscreen also got a minor update.
It’s not a huge difference, but there are some noticeable changes. The polished metal look is gone, and replaced with an Apple classic: brushed aluminum.
Little changes like these are what is often so interesting about Apple. I’ve always found these gradual changes to be a bit fascinating. For instance, I didn’t really notice a lot of the differences between Mac OS X 10.2 and releases after that. I’d notice a change here or there during a major update. However, if you look back at 10.2 now, it looks completely unlike the current version of OS X.
