Yeah… There is another MIUI Android ROM cooked by xda-developer, Jayyy ~ MIUI-Star. It is in beta stage right now. So do expect to see bugs flying around. But still no harm to try it out…
Default Internet Browser is not working. But Miren Browser is the one that you should be using if you are using this ROM. Do check out xda-developers for latest information about this ROM.
