This is Sprint - it is a recorded telemarketing call trying to sell downloads for Android users...I got a call from them at 5:53 a.m. Central Time on December 11, 2012.  It is against the law for telemarketers to call people before 8:00 a.m.  I used to be a telemarketer.  I called the number back and got a voice mail (how convenient).  I told them to remove my number from their marketing list.  I also told them it was against the law to call people that early, and if I receive another call like this I will be reporting their company.  This spam telemarketing is getting outrageous!!!
