buying cellphones from internet

has anyone ever bought a phone from the internet, I dont mean ebay, tmobile,vrizon or any manufacturers. i found a bunch of sites like Wirefly.com and ushopwireless.com that are offering the phone I want for free after rebates, which is cheaper than what tmobile wants($299) Has anyone ever bought a phone from a internet store and how did the deal work out? did you get the rebate? did you keep your Phone#? was there any other fees involved besides the ones the site says? I have tmobile now since 2001 and its good coverage and all I just want to step up to a better phone

Hmmm? no one buys cell phones online here? no horror stories, no "My buddies" stories? nothing?

if you have t mobile, just buy a phone made for the t-mobile service, then swap out your sim card....
