If I do a factory reset, will the phone be running the version before the update, or will it still be v2.2.1? Ever since I installed the 2.2.1 update back in December, my phone has been restarting itself, and most recently, disconnecting me mid way through phone calls. I've decided this is caused by the update not getting along with all the customisations I added before the update, so I am going to do a factory reset. Also, if it removes v2.2.1, do I want to reinstall v2.2.1 (this time before I install my apps)? I know this update was pulled for a good reason, but I'm thinking thats only because it is incompatible with phones that have already been used for 2 months before being updated.
