Choose a 6- to 10-digit number you can easily recall, but make sure it's not easy for someone else to guess. Avoid using parts of your phone number or a birth date for example.

      BEST PHONE EVER MADE HANDS DOWN

      Posted by KOREANHEAT from ATLANTA on 10/15/2011

      SIRI, SIRI, SIRI WHAT A AMAZING FEATURE. APPLE HIT A HOME RUN WITH THIS. BASICALLY GOOGLE SEARCH BUT WAY BETTER AND IT ACTUALLY UNDERSTANDS WHAT YOUR SAYING. IT ALSO HAS A SENSE OF HUMOR, WHEN YOU GET ONE TELL IT, I LOVE YOU, AND I NEED TO HIDE A BODY AND LISTEN TO THE GREAT RESPONSES. GOT MINE ALREADY AND GETTING MY OTHER EVO AND EPIC SWAPPED TO IPHONES ALSO. I SEE WHY THE HYPE IS SO BIG. QUAILTY ALL THE WAY AND THE BATTERY DOESNT DIE IN 12 MINUTES LIKE THE EVOS. YEA I HAVE THE EXTENDED BATTERY AND IT WORKS BUT NOW MY EVO IS 792 LBS. TOUCH PAD WORKS GREAT. MY ONLY WISH IS A LIL BIGGER SCREEN.

      I would recommend this to a friend!

      GREAT PHONE!!!!

      Posted by Meesha3 from Altamonte Springs, FL on 12/6/2011

      Siri is awesome! I am a sales rep and do a lot of driving. I am able to do emails and texts faster and safer with Siri. I just tell her to send it for me. Finding locations is faster and better than ever, as I just ask Siri. She is just amazing!!!! Can't wait to see what other stuff that Apple can come up with.

      Great phone in every way!

      Posted by Dashiem from Conyers, GA on 4/24/2012

      Overall the 4S is a great device especially for a beginner to the data world. I use it as an assistant, game station, and phone. Phone is very fast on WiFi and a bit slow on Sprint 3G but that’s not related to the phone.. My only complaint is when I stream Pandora the phone gets hot after awhile. I expect the battery to die fast but not get hot. Other than that… Great work Apple!

      I would recommend this to a friend!
