I know alot of people that use the Galaxy. They are very happy with it and some people that I know are switching from Iphone to Galaxy. I guess the display is something to die for. I would go for Galaxy because it seems that alot of people are happy with it.
Does it come with a disc? If so you could probably boot it up off of the disk than restore it from there. I had the same thing happen so I just used the disk and restored it from there.
They all pretty much do the same thing. I have an iphone and any cheaper phone works just as well. It just matters about reliability and if you think that what you buy is worth it. Look at the reviews and see if that compares with what you want in a phone.
Yes they are very good. I have one. It charges VERY fast for my phone on long road trips. It also can be used multiple times before being needed to be charged.

I think this is the way to go. You have a case and its charging at the same time. Also, check out enercell.
I dont think so. I know that if you have icloud running it will be saved "up there" other than that I only think that it will stay on the phone. How much does a phone go for with flappy bird on it anyway?
