I have an iPhone 4 with Sprint and I just started receiving these calls a couple days ago. I have been reading you guys' posts on here and we pretty much ALL have the same things in common: All with Sprint AND ALL have either iPhones 4 or 4s'. The only difference is I see is that instead the first time i got a call from this number it was actually my older brother calling which was REALLY weird because his number is programmed in my phone so every other time he calls it shows up with his name and number (area code first). However, this time it was him but from this weird [***] number. Ever since then, I've been getting calls from this number non-STOP! When I do pick it up they just either hang up or its dead air and then hangs up. VERY annoying! I opened up a case with Sprint tech support and they had NO solutions for this issue other than to do a master reset (which would just erase all media in my phone not backed up to icloud) or change my number! Not cool at all.
Call comes in and registers on cell phone as unknown but when you select it out of call log to call back it shows 865 6696. Since I'm in a 205 area I am assuming it is a 205 number. Yet when I call it back it says number is not in service. This has been occurring 4 or 5 times a day for the past 3 days I am concerned about this type of call.
