I'm thinking of buying an Optimus Black but as you know it comes with Froyo (2.2), so I'm thinking of upgrading to 2.3.
Do I have to root my phone in order to upgrade to 2.3? Because I've read on other forums/posts that rooting gives you the possibility to install custom Android versions (same thing as custom ROMs right?), but is it really necessary to root to make this update?
I've got a few things mixed up in my head about Android and if I wrote something that isn't true please correct me.
