There is more issues then the ones you have described. Like capacitive button layout not working, noise calculation issue, audio echo issue & bluetooth audio issue.
True. We can all go flash the galnet version if we ant but as shep mentioned all the issues do apply. I've actually been working on a MIUI port myself. Everything's working with the exception of the echo others hear when I call them. Sounds great on my side but my Girlfriend has been getting pissed. LOL. So I only use miui when were both at home. Fml.
