It's the Infuse, and it seems like ATT is getting the kewl fast Android handsets while Verizon sucks Apples stem and holds back releasing any new handsets while they attempt to unload their overstock of iPhone 4's.
Fact is, is yo do not live in the signal range of one of the 39 cities that has 4G LTE service, yo will be getting 3G on your 4G phone, and if Verizon goes to teired pricing, you will be paying extra for your 3G phone service. Then in June or July when they really start rolling out kewl 4G phones with dual cores and better features like HDMI out, your Thunderbolt that you raced out to buy will seem lame... oh wait... it already does!
