The Verizon plans are all set up to benefit the family now. For individuals, it really sucks, imo.
I don't know what their prices on the iphone is, haven't looked that up. The only reason you would need a 32 gig though, is if you wanted to keep movies on it as well. I've got plenty of space on my 16 gig for music and apps, but movies usually run about 1or 2 Gigs each and eat up space. I have a 32 gig iPod touch and it's a struggle to get it full without throwing a crap ton of movies on there.
It's a share everything plan now, so really, imo, if you are a single user, I'd look somewhere else. Verizon is really ripping people off right now. For my wife and I it works OK. We have unlimited talk and text and 4 Gigs of data, but that comes at a pretty healthy cost $40/phone/month + $70 for the Data. $150, so really not bad for us, since before the share plans, we'd have been at $160/month total, plus having to pay for text and calling at that price.
For a single though, it's going to be $40 for your phone, + at least $50 for the cheapest data plan. My wife and I rarely hit the 4 gigs, but all it takes is one of our kids to decide to watch netflix and boom, there goes the data. And honestly, $20 for an extra 3 Gigs just gives me peace of mind of not going over.
That being said, I think in the end, all the iPhone carriers seem to be the same price, maybe less for data, but more for phone. I shopped around quite a bit when I got my iphone and in the end, you are only saving a dollar here or there depending on who the carrier is.
Also, unless you are a big Apple guy, don't get me wrong, I like my iPhone, but I'd really consider the Galaxy IIIs. That's what my wife has and to be honest, I wish my iPhone 4s was that nice. If it wasn't for work and already having all apple stuff for my personal use as well and owning a million apps already, I probably would have went with the Galaxy.
Other than that, I am very happy with Verizon though. I've never had a problem with their service and I've been a customer since they came to the Chicago area.
