Well I'm kind of leaning towards the Galaxy S3 only because I already have another Android-based smartphone and I could move the SIM card from my current one to the other one, so it'd be a lot easier to move a lot of things over, but at the same time, I'm getting kind of tired of a lot of companies only making apps for iOS and not for Android. I also like the the iPhone 5 allows 8 hours of talk and/or web browsing, whereas the Galaxy S3 only offers around 5.5 hours of web browsing (granted, my current phone only lasts around 3-4 at the point because it's slowly dying, lol).
But I do have some time to figure it out cause I'll probably wait until November to upgrade (that is, if my phone keeps charging until then) and I'm in Texas cause then I'll just change over my phone & number at the same time.
yeah, realistically/luckily for you, you do have the time your better to wait for the iphone to be out long enough to get reviews so you can compare them side by side (i wasnt that lucky so i had to buy a new phone and have always been iphone oriented lol i have a mac so naturally for me iphone was a simple solution and decision )
