Not really sure why everyone are giving bad reviews on Sprint. Yes, the talk coverage are small and bad, I get that, I complain to them all the time too, but there's nothing we can do to change that, so deal with it.
I am all for the unlimited data coverages. Most of us don't own a laptop anymore, so we are on our phone 24/7. I watched movies, listen to radios, check my e-mails and etc, I used it everyday and it goes over to the 2GB mark every cycles, and my speed is still the same, sometimes faster too.
I come to this place for any technical problems I have with my phone. I used to have the BlackBerry Curve 8330 and it causes problems all the time, I came here for solutions and they usually fix it right away within 48 hours after I dropped off my phone.
I've been with Sprint since 2000, I have my ups and downs with them. But be patient, none of the phone providers out there are perfect. You have to invest your time and money to find out what's good and what's not. Good luck!
