How 4G phones will change the way we use cellphones

Recently I took the Sprint HTC Evo 4G down to Philadelphia for a weekend, the closest 4G zone to New York City, to see what all the 4G fuss is and will be about.

First, Evo's drool-icious pool of future tech makes it a groundbreaking device — not quite the shock the original iPhone was, but close. Evo's 4G connectivity, front-facing camera, HD camcorder, and especially its multi-user mobile hotspot capabilities, are all features future high-end cellphones will emulate.

But my Philadelphia experiment has revealed to me that 4G will mean more than just faster Web browsing, faster video/music/photo uploads and downloads, faster pussycat kill kill. 4G speeds and the capabilities they enable will literally change our lives. Here are five ways 4G technology will change the way we use our phones.
