I tried adding a second Live ID... but it didn't seem to do much? As in, I could not switch the Xbox Live to use that second ID.
There is no way for her to use Xbox Live games I bought on MY account/ID using HER Live ID/gamertag unless she buys them herself, right? In other words, in a scenario where the phone is set up with MY Live ID/Gamertag as the primary with purchased games, and her Live ID as a secondary, it's not like she can play those games as HERSELF/her gamertag, right?
Same thing with Zune Pass... she can't access that as HERSELF, only as me through her phone if I put my account as the primary one on her phone, right?
So it's kind of pointless having her be a second Live account on the phone then? I might as well just buy two copies of the games and give her own Zune Pass now that they lowered the price to $10/$100 a year.
Please correct me if I'm wrong here. I wish they hadn't made this so incredibly unfriendly for families.
