Sprint was the premier carrier for the Samsung Nexus S and then Verizon ended up getting the new Galaxy Nexus first. It turns out though that Sprint will also get a LTE version of the Galaxy Nexus as they announced today at CES. LTE is new for Sprint and will launch before the middle of this year in Atlanta, Dallas, Houston, and San Antonio.
The Sprint version of the Galaxy Nexus from Samsung will likely be the same as the Verizon version, but Sprint did announce it will also have support for Google Wallet like their Nexus S 4G does right now. I actually used Google Wallet on my GSM Galaxy Nexus today in Vegas to buy a sports drink in the hotel vending machine because I had no cash on me, but my phone is always with me.
A benefit of waiting for the Sprint LTE version of the Galaxy Nexus is that you will get to take advantage of their unlimited Everything services. The one issue will be that you will have to wait for their upcoming LTE service to roll out to your locality.
The more I use the pure Google experience on my Galaxy Nexus the more I become a fan of the Ice Cream Sandwich interface with no customized manufacturer skins.
