Quick answer,
You can't upgrade to 4.3 because Apple is no longer signing it, so you'll have to upgrade to 5.0.1

4.5 never existed. So it's impossible to upgrade to.

Hope this helps! :)

I honestly wouldn't have a clue, but I'd imagine it wouldn't hurt anything.

Maybe calling your provider and asking them this question could get you your desired answer. :)!
