I was reading that people that want to upgrade to the Evo 3D but not up for an upgrade, can call Sprint (though some special number I think) and they are allowing an override so you still can get it for $200. Read it on XDA Evo 3D section. Worth looking into, as I might for the 2 other lines on my account. Just debatting if I want to stay with my Epic, or give it to my wife and get the 3D for myself, or maybe even wait for the SGII.
Also, anyone have any experience with transferring a phone from one line to another? I bought the phone though Amazon and know some 3rd parties will charge you if you do, but not sure exactly how that works... read about it some, but wanted to see if anyone has some experience.
