this is going to seem random and off the wall, but if anyone is crazy and ocd like i am about their iphone they may find it helpful. i clean my phone weekly. take it out of its case, wipe it down, and get all dirt, scuffs or grime off of the back. i recently found the best cleaner that i personally know about. its called sheila shine. its an all purpose shiner and protector. i was sketchy at first but this stuff truly makes your phone shine and glisten like the day it came from apple. i apologize for the rambling but i just thought id share with all of the fellow iphone enthusiasts
