Phone was off.  Saw blinking green light indi aging missed call.  Turned on phone.  Screen I.dicated a download had been made and I should push update button, that download begin and last for 5 minutes and then would turn off phone to install update.  It did NOT indicate what program the download was for and from whom or what it had been sent.  I ignored the update notice but went to check my missed t all.  Found the 209 number listed.  Called it but number NEVER RANG even though it indicated duration of call was 14 seconds when I disconnected call.  I am leery that the unsolicited "update" and unknown caller were connected.
