So this question gets asked occasionally and in different locations -best+cell+phone+provider. And of course the best cell phone search has its own subreddit (/r/iphone and /r/android) in constant motion.
Now I am looking for my two year data/hardware relationship. I saw a nice inforaphic on Virgin Mobile (Here). The phone and the service has to be solid in North America (not just the US). I love the iPhone camera - wouldn't mind it again. I like the iPod. I read a lot of news. I play one game...though not much recently because the last four boards (not sequentially ordered) are too hard for me to beat.
New mobile telephone and service - homebase is South Florida, USA. Virgin? Stick with AT&T? Go with a month to month throw away and just buy a badass hand unit? Get a mini tablet with a cell connection and go skype?
