I give this phone two and a half stars. I bought the Samsung 660 b/c I wanted a lightweight phone with no camera (I was told by the Best Buy guys that the camera takes up extra battery life even if you don't use it). I still wanted the Vision capabilities, however, so I could download my own ringers and screensavers. So, this phone seemed to match up with what I wanted, and in features alone it does.Another Amazon reviewer said that Sprint users have to pay extra for voice dialing--that is incorrect. You access the voice dialing by pressing the left blue button on the square keypad (next to the "OK" button). You can do voice dialing or numeral dialing. It's really cool.Also, I called Sprint about the downloaded ringtones "expiring" after 3 months, and the rep told me the ringtone only expires in your Download Inbox account. So if you download the song to your Download Inbox and then upload the song onto your phone within 3 months, the song is on the phone permanently.But I am really annoyed about my reception problems with this phone. My previous phone--a Sanyo 4900--was stolen, so I needed to get a new phone right away. I think I should've stuck with Sanyo b/c I never had the reception problems with Sanyo that I do with Samsung. Nearly every day a call gets dropped, normally when I'm in my apartment. But calls were never dropped in my apartment on my Sanyo! Also, sometimes people call me and their voices sound garbled, like they're under water. I have to move around to a different area in order for their voices to come in clear again or hang up and call the person back. Other times the caller's voice sounds "fuzzy" and I can't understand what the caller is saying.I wasn't able to find a Sanyo with the clamshell design I wanted *without* a built-in camera, so that's why I went with Samsung. But I think I should've considered the Sanyos more just to have decent reception. Oh well, in eighteen months Sprint told me I'll qualify for another rebate and can upgrade my phone. Sigh.
