Appears as a missed call on my phone at work.

It's sprint, trying to sell a phone. But they're trying to sell it to you at a lower rate then normal. I got an LG Optimus for free with the extra discounts they gave me.

If youre in the market for a phone from sprint and you've been a customer for a while (the lady would not stop saying "just because youre a loyal customer!!....I admit it got irritating but it got the point across)
Then pick up the phone, or call back (like I did) and give em some info and get a new phone. Was easy and she answered all my questions. Was very informative.
