I currently have 3 VM Optimus' and 1 Rumor Touch. We are getting 3 Galaxy S3's through Sprint and eliminating the 3 Optimus' but keeping the 1 Rumor for my wife. She has no desire to go Android but her phone was bought last and is $35 per month. The 3 Optimus' are all $25 per month grandfathered. My question is, can we change her Rumor to one of the Optimus accounts and pay $25 or will I be stuck with one $35 payment after we get the GS3's?
