Im using 2.3.23 Miui. The 3g data toggle on itself sometimes even though we already off it manually. So please fix this bug or is it any other way to off it permanently.
There is no any custom miui rom. Miui already updating every weekly for the rom so about the performance no need to worry. Any its already smooth, fast & stable the current version. U can download from http://www.miui.us/
