Its here!!! XDA member febycv has released a Beta MIUI 4 ROM (unofficial port), or MIUI based on the Ice Cream Sandwich framework, for the MyTouch 4G.

Pre-Installation Requirements
- Installing/Flashing this ROM will erase your apps and data. So, it’s very important you back them up, before proceeding further. To backup your apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. Restore APN settings if Internet isn’t working for you. This Android backup guide would help you. And if you’ve rooted your Galaxy S, you can save application’s data too, using Titanium backup (free app on Android Market) to backup apps with data. And use this app only again to restore those apps with data.
