Whatever happened to “Do not heat your phone. If needed, you can use a dropper or syringe to inject isopropyl alcohol (90+%) around the edges of the back cover to weaken the adhesive.”?

I'm assuming that "IPA" stands for "IsoPropyl Alcohol" and not "India Pale Ale"

I would love to know that detail as well.

Just wanted to give some feedback about this a couple years later. Nope, it doesn't look gross in the slightest and this is after HEAVY, real-life, everyday use/abuse. It's still as optically pristine as the day I unboxed! it :)

I'm assuming you're referring to the T-Mobile version of this phone. No, it's not just the antenna that's different, but the radio as well. They both have to be matched.

No, I'm almost certain the rattling noise comes from the camera autofocus mechanism. You can hear it when you use any camera/barcode application.
