So, I went to school today, and everyone was talking about the new iPhones. So I said, you wanna see what the new phones look like? Just look at mine!
They were totally convinced I had iOS 7. I pointed out the new icons, the dots replacing bars, the new lockscreen using Move2Unlock, and the parallax wallpaper with DeepEnd. One person asked about multitasking, so I showed him CardSwitcher.
Another said he's thinking of switching to Android, and wanted to know if iOS 7 would change his mind. I didn't have time to get into it, but I did point out that anything you can do on Android, you can accomplish by jailbreaking.
Since I'm keeping my jailbreak on this phone, I won't have real iOS 7 on it, but I can at least look like I do, and have much of the new functionality, while keeping my jailbreak. (I'll be upgrading my other devices.)
I've had others notice in the past few weeks, like when I set my phone down next to the cash register in a store, the clerk recognized iOS 7.
