If you've seen a few screenshots of iOS 6, you know Apple's made some nice interface enhancements, such as a better sharing menu, dialler and music player. If you've got a jailbroken iPhone running iOS 5, you can bring those changes to your device right now.
Note: Many of the tweaks mentioned here were designed for iPhones and iPod touches with retina displays only. They may not work for older devices.
Add iOS 6's Improved Sharing Menu
One of the smaller but very welcome changes in iOS 6 is the way you share things. Instead of getting a long list of buttons, you now get a grid of labelled icons that looks a lot like your home screen. This is a better, more visual approach to sharing. To get this feature on your iPhone right now, you just need to search Cydia for a tweak called iOS 6 Photo Sharing Menu (Free).
After you install it, you don't need to do anything other than try to share a photo. Open up your Photos app and give it a try. You'll be presented with the grid you see to your right. You'll notice it includes Facebook sharing, which is a new option in iOS 6. While this button won't work as seamlessly as it will in the real upgrade, it does function. You'll just be sent to Safari to authorise Facebook sharing through the tweak and then you'll be able to directly share your photos without issue.
Add iOS 6's Interface Elements
If you really want your iPhone to adopt the new interface elements in iOS 6, you're going to need the iOS 6 Winterboard theme. To get it, just search Cydia for iOS 6 and it'll come right up. You can install elements, such as the music player and dialer, separately if you want, or you can just get the entire package. You'll need Winterboard to actually use this theme, but if you don't already have it installed, Cydia will take care of that for you when you attempt to add the iOS 6 theme itself.
Once you've got everything installed, your device will reboot. When it's back up and running, look for Winterboard on your home screen. Open it up, check off the tab labelled "iOS 6," and tap the Respring button. Your home screen will reload and you won't notice anything new outright, but if you open up the Phone or Music app you should see the changes right away.
