Question: is this a smart phone
Document: bought this for my mom - its working fine for daily use and gets good reception - not a fancy new smart phone but reliable enough with basic smart phone features
LG's vortex vs660 stands out from the market competitors. Beats all other smart phones of its generation. I bought this one for my wife and can't get her to trade me for my LG (older flip phone)
My wife is relunctantly tip toeing into what ever century we are in. She is slowly picking up on the workings of an android smart phone. I think she's having fun at it  but hasn't had it very long. It fits her hand fine, the battery seems to last longer than my Droid X  between charges. I hope time doesn't have any bad news in the future.
Just don't buy the phone. Save yourself the headache..
this phone freeze up to much and it slow on downloads there is more problems with this phone then it is
bought this phone to replace one of the same  model that i have had for over 2 years.that is all.
they said it was a htc which it's not can't get 3g and the phone is small so it hangs in my shirt
This phone is well worth it. Don't listen to the other reviews about the negative feedback about this phone. Just get it.
This is by far my best cheapest android phone. For beginners its great but for adults I suggest bigger and more expensive
