Is there an iOS-like skin for Android and/or a launcher with an iOS theme?
Espier Launcher is a homescreen replacement that mimics iOS quite well, and still allows for some of Android's features to shine through (Widgets, customization, etc).
Unfortunately, it's apparently built by a small Chinese dev shop, so it does have a few quirks. For one, it intalls some bloatware app store that's all in Chinese, although it's easy enough to hide it from the launcher. There's also some weird mis-translations in the app's settings. Despite these shortcomings, it's a faithful reproduction of iOS's homescreen, and the folder/scrolling/long press animations are spot-on.
MIUI is one of the most popular Android ROMs in the world. It is based on Android 2.3 and 4.0, featuring better experience and richer themes. MIUI is updated every Friday based on the feedback from its users.
