you should better rework YOUR version then fighting with users....as I posted (see quote): these are small issues just in your version, original from miui.com is running without any bugs
v4 for SGS2: your version is crashing when using 2g/3g toggle and Settings - About Phone - Status....it works flawlessly with original version from miui.com...so some mistakes in copy/paste ;)
that really doesn't matter, Andy...your work is great and highly appriciated!! I could not do all these amazing smali-editing you and roenano are doing!!! ;)
