Macharia I actually enjoy MM now, you could do a backup first.. Then apply the update, then do a factory reset or if you prefer, just do a backup and using XC run a software repair.

Okay thanks demigod. So they've fixed all the bugs, like the unresponsive screen? Are there any I need to know about? Do I factory reset before or after the update? I prefer updating via the software update setting on the phone.
