...only if you intend on ever using the phone again. I grew up opening oysters, an Iphone ain't jack. Also, I believe that I pointed out in my post that this very concern is why God gave us hammers (tire irons, rocks, boots, et al) and closed metal cans (AKA a Faraday cage - like a sealed metal paint can half filled with rocks and thrown into a rain filled creek), but I still prefer the smashed, baked pieces at the bottom of a coal mine. I will point out for the pedantic (and Sheldons out there) that beating on a Lithium battery is not a good idea, so don't do it in your vehicle or around any sign that says 'Infammatory' or 'No Feugo"...the plus side being that if you do manage to ignite the battery, good luck with anyone EVER pulling forensic evidence off of that hot mess (another good reason to have a handy empty paint can).
