Just to let you know, have the latest update of CM10 installed over the air. Everything went fine. Have not experienced the missing gallery as described by others,, but the phone d id reboot when using the navigate to destination service on Google now. The excessive in call volume of the previous release seems to have gone now, just had an extremely clear phone call. After one days use of latest update noticed slight text corruption of the drawer on boot up but seems stable now.
Hi There, I was in exactly the same position as yourself a few months ago. But with a bit of help from some very helpful people I was soon swapping my firmware on
a regular basis. My distro of choice at the moment is CM10 purely because it does everything that I need it to do and more. Of course there are a few ittle problems
still to iron out but nothing like the problems with Huawei's own version of ICS. Your suspicion that CM9 is a good stable ROM is of course true so, if one day you are
feeling brave then, follow the advice on here download and install it and, like most of the people on here you will have a great big grin on your face the first time your
phone boots into it's shiny new ROM .............. :-)
