A few days ago my new iPhone 5 arrived, so I handed down my 4S to my fiancé (she originally had a 4). Before the switch I completely erased everything, put in her SIMM card, and restored it from her iCloud backup. Two days later, she downloaded the ESPN Scorecenter App for the first time, from her iTunes account, and upon launching it, to my surprise, it signed in under my username and password, and had all my team alerts and settings ready to go. I vaguely remember a year or two ago after turning in my 4 to the Apple Store for replacement under warranty, not long after that my team alerts on the ESPN App just constantly started disappearing until I finally changed the password (my guess is they sold it as a refurbished phone). And again, everything on the phone was completely erased before it left my hands. Has anyone else ever experienced that with this app or any other app and know why it might be happening? I am planning to sell the old 4 on eBay this week, and it concerns me that some random person could buy it and install an app that was previously on there and pull up my or my fiancé's accounts.
