Your Account PIN and Security Question AnswerClose

To enhance account protection, Sprint requires you to secure your account with a 6- to 10-digit personal identification number (PIN).

Tips for creating a secure PIN:
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.

For your protection, you can't create a PIN that contains:

Viewing, modifying or retrieving your PIN:
You can easily view and modify your PIN. If you forget your PIN, you can retrieve it in several ways:

      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!

      The apple of my eye

      Posted by Poza2011 from Boston, MA on 10/20/2011

      Had the very first iPhone, was due for an upgrade. Glad I waited for this latest model. Couldn't be happier with the new features and the way you can now customize some of these things. Worth the wait.

      I would recommend this to a friend!

      BEST PHONE!

      Posted by Steph0690 from Miami, FL on 10/20/2011

      This is the best phone I have ever had. I've been patiently waiting for Sprint to get the iPhone and I'm so happy they finally did. I have the unlimited data plan and I can say it is very worth it. I just upgraded from a blackberry tour 9650, what an upgrade. The touch screen is amazing, it is super fast, the browser is super fast, netflix and youtube stream perfectly. The battery life is decent. If you only use it for calling, texting, and e-mail it lasts a very long time, but if you are constantly surfing the web or playing apps you will notice the battery drain. I;m getting such good reception with this phone, much better than with my blackberry. To save the best for last SIRI. Siri is great I can now respond to text messages while driving safely. She understands everything I say clearly. Great phone!!! I don't think I'll ever own another phone other than an iPhone!

      I would recommend this to a friend!

      Don't Hesitate BUY This IPhone

      Posted by NYMetsFan from Tampa, Florida on 10/22/2011

      This is my first IPhone. My wife has the IPhone 4. I fell in love with her phone. Verizon service is the best although expensive. I had the Droid X but it CONSTANTLY crashed especially when using Google Navigation App. The only app the IPhone really needs to add is a similar but better App that the Android has (Google Navigation). Don't pay for VZ Navigator. It is not worth it. Map Quest has a decent free app on the IPhone. The phone is FAST and the personal assistant is "Geeky" but VERY cool. Buy this and get rid of your IPod Touch. No need for it any more.. Get the Smuge Proof Zagg Screen Saver! Let Best Buy Install It LIFETIME Waranty!

      I would recommend this to a friend!

      Amazing Phone!

      Posted by Alaska241 from Los Angeles, CA on 10/24/2011

      I love this phone! This is the best smartphone I've ever had. I had bought an 3GS for my daughter and myself last week and found out it was very slow and sometimes it even dropped lots of calls! Though my daughter is fine with the phone but I am not. I ended up returning the phone and getting an iPhone 4S instead. It works perfectly and fast and in my condition, it never dropped a single call. For people updating from 4, hold on and wait for 5! But if you're on a 3 (or lower) or 3GS, update to 4S because it is completely worth it.

      I would recommend this to a friend!
