hi there, i am new to this forum. hoping someone can help me understand the most economical way to upgrade my phones and plans. i have 2 older phones and a Free and Clear Family 500 plan ($45) plus Free and Clear Add a phone ($20). i have no data service. we want to upgrade to 2 EVOs. is it even possible that i keep my old plans and add a data plan to it? and would i even want to do this? or just go with an Everything Data Family? at least i think that's the most economical plan for a 2 phone family. and i've been reading about people getting the mandatory $10 4G fee waived or other plan discounts. i am assuming you have to buy your phone through sprint directly to get these fees waived? are the reps at best buy or radio shack authorized to give discounts? if i buy my phone from a 3rd party, can i then go back to sprint and get these discounts? suggestions? this is so confusing. TIA!
