Wife is primary and has HTC Evo. she is coming up on 1 year in like 10 days. I understand that makes her eligible for some sort of upgrade discount. We have 4 phones on the Sprint Family plan - all android. but only she and I are 4g. She's got an HTC Evo and I have an Samsung Epic. I came into the plan like 4 months after her. This morning, my EPIC was seriously damaged.. LCD all cracked up, but it works somehow. Is her 1 year upgrade eligible for full discount? I understand I can't become the primary without incurring some 3 month wait? Can we switch phones on the system and switch back after her upgrade? Any way to navigate this? And will the Sprint store even care about what phone she is upgrading from or if it matches what's on file? They tracking anything? Thanks in advance!
