If you need to ask for a full tutorial on how to install NITDroid then

-YOU SHOULDN'T BE INSTALLING IT-

And as for v11 if you haven't done the research on it already and understand it is a beta release for testers -ONLY- then again,

-YOU SHOULDN'T BE INSTALLING IT-

And if you are not confident in reflashing your device if it all goes horribly tits up then,

-YOU SHOULDN'T BE INSTALLING IT-

and if on the other hand, you don't know how to google for answers and where the NITDroid forum and Wiki is then, guess what?! Thats right!!!

-YOU SHOULDN'T BE INSTALLING IT-

And if you don't understand and already know that telephony functions -WORK- but no sound is routed from the microphone therefore calling is useless then

-YOU SHOULDN'T BE INSTALLING IT-

so, calls DONT work, WONT work, v11 is TESTERS ONLY, BETA release, and you need a modicum of EXPERTISE to install AND uninstall so

-DON'T BLOODY INSTALL IT-

Christ on a bleeding bike. I give up.
