My trusty G4 which has served me flawlessly since 8/15 went into the dreaded boot loop tailspin last night. This phone is a 505. Everything gets stored/saved/downloaded to a 200GB SD card as well as Carbonite so nothing of importance is lost. A replacement is already being expedited from AT&T. Using my G2 until the "new" G4 arrives. Keeping fingers crossed. Will update everyone when she arrives.
