As we reported yesterday, Wirefly is offering the Nexus S 4G at the mind-blowing price of $99 for anyone willing to sign a new contract. Of course for those that can’t/don’t want to sign up for a new line, the Nexus S 4G will still be offered at $149 for qualifying upgrades. There’s no telling when this offer may end, or if it’ll end at all. One thing is for sure though, if you want this phone go get it while supplies last!
