Multiple Apple ID's on separate devices
I have different Apple ID's on my iPhone an iPad...no clue how or why but it has been that way forever. Purchases and subscriptions on both devices are made with only one Apple ID. I would like to be able to sync various apps thru iCloud but it means changing the Apple ID on my iPhone. What are the pros and cons? What will I lose and can I get it back after the switch?
