If you've ever had a Sprint SERO plan, you know how damn hard it is to let it go. The old Sprint Employee Referral Offer was pretty easy to come by back in the day and brought super-low-price contract plans. But as higher-end (and more data-hungry) device launched, Sprint began to move people off of SERO.

Looks as though these cries have been heard, and Sprint has decided that as of Oct. 1 it will include the Samsung Moment, HTC Hero, HTC EVO 4G and Samsung Epic 4G in the SERO Premium plan. There is one catch -- users will have to be on an existing SERO plan before Oct. 1 to qualify for the SERO Premium plan. [SprintThanks, Malatesta!
