Sprint will apparently announce the pre-paid phone this week.
Though the majority of iPhone rumors these days are centered on the next iPhone, iPhone 5, that device isn't expected for a few more months. Though it could make an appearance at WWDC, just like iPhones 2G through 4, it's widely expected Apple will instead announce the iPhone 5 on the one year anniversary of the iPhone 4S in the fall. So what do we have in the mean time? Rumors about the current iPhone heading to new places.
According to the latest rumors, the iPhone 4S will soon arrive on Virgin Mobile. Not only that, but the phone will be available on a PAYG (pay-as-you-go) basis. The news comes courtesy of a report in the Wall Street Journal, which cites people familiar with the company's plans in reporting Sprint will announce a pre-paid iPhone for its MVNO subsidiary. That's right, Sprint is apparently following Cricket into pre-paid iPhone territory.
Sprint hasn't had the iPhone for all that long. The company only became an official carrier with the launch of the iPhone 4S last October. However, its thought that the provider struck a hefty deal multi-billion dollar deal with Apple that spans four years. The WSJ hints that Sprint's move to put the iPhone on Virgin Mobile could be a strategic move to ensure it doesn't fall short of that commitment.
If the Wall Street Journal's sources are correct, Sprint will announce Virgin Mobile's pre-paid iPhone before the week is out. Stay tuned!

Besides, I bet these pay as you go plans are a total ripoff.

I remember doing the math, and it just didn't add up to much of a discount to go with the PAYG.
yea my wife's android phone on virgin mobile... she gets unlimited data, unlimited txt and 300 talk mins that she uses maybe 10-15 of a month for 25 bucks such a rip off. i use sprint and she usually has the same coverage as I do on my samsung galaxy nexus that I pay 64.95 for unlimited data/txts and 450 min on sprint... which is still a better deal than big red or at&t
I wonder if this will cost an arm-and-a-leg though because an iPhone without a contract before this costs $500-600.
oh and phone prices. we paid $200 for a samsung galaxy intercept about a year and a half ago which she still uses. so compared to my $200 galaxy nexus she's cost alot less... though granted her phone isn't as good
Virgin Mobile
Straight Talk
Cricket
Metro PCS
T-Mobile
and others
Unlimited everything on a 2 year contract with Sprint/Verizon/AT&T is going to cost you about $100/month or more.
Neither Verizon or AT&T offer unlimited data.... Only Sprint and T-Mobile do.
Straight Talk depends on the phone you buy as they use Verizon, Sprint and T-Mobile's networks. You can get an Android phone with Straight Talk on Sprint or T-Mobile's networks but not Verizon's.
Boost Mobile is also one of Sprint's pre-paid companies. Boost Mobile will discount the monthly price if you pay "on time" every month. It's actually a pretty good deal since it can discount the price by $10-15 a month over time, but the initial service price ranges from $50 to $60 depending on the phone. The phones are pretty reasonably priced though.
How can you be retarded at the age of 30?
Mod edit: Should be retired, not retarded (if you don't see the obvious).
Definitely the way to go, unless you absolutely need to rely on a data connection (work purposes, etc). VM's is sufficient but certainly less than desireable.
