What about MIUI Rom to Galaxy 5


It is the first Android smartphone that falls within the 10K barrier. It can be effectively classified as an entry-level phone, and more importantly, it is the lowest priced proper smartphone (with a touchscreen) available in the market. The Galaxy 5 supports 3G, Wi-Fi and it even has a built-in GPS chip. It has 170MB of internal memory and comes with a 2GB microSD card.
