Ok so my upgrade with Sprint is coming up and I am getting the iPhone 4 to FINALLY get rid of my crappy Samsung Moment! lol I know the features of the iPhone and all that but with the iPhone and phones in general, does the phone make a difference when web browsing or data connectivity in general? My Samsung Moment has data lock ups, ocassionaly slow to load etc. I guess what I am really asking is how much is it the phone and how much is it the carrier when these problems occur? (Sprint in my case) I am not to fond of Android anyway.
