[1.1.3] making sure it's safe to upgrade to 2.0
I am running 1.1.3 on my phone right now and it was orignally a 1.1.2. obo My baseband is 04.03.13_G I looked around the site and there is all kinds of ways to upgrade to a newer firmware but nothing on my exact situation.
I don't remember how I updated it to 1.1.3 but I know it was an early method. I want to know what my best options are to get it back to default 1.1.2 or upgrade it to 1.1.4 or 2.0
I asked before and was told not to do a restore through ITUNES as the baseband is wrong, etc... I am trying to figure out my options! Thanks in advance
