New to posting but I've been reading all of the threads since day one.
In talking with some coworkers today about texting and technology, I'm wondering if EA did not actually use text messages or IMessaging if he had an iPhone. Hear me out, a lot of people Christina's age use messaging apps like Whatsapp and Kik. Maybe EA knew that there would be no text messages via record on his data plan or cell phone bill because he knew he used a messaging app, thus the reason to completely scrub and restore his phone to default settings. Some of these messenger apps don't even save the chat information to a central server unless you manually backup chat conversations to an iCloud or Google gmail account. Just throwing this out there....maybe he happened to backup this info to his personal accounts, even if his phone logs come back clean.
