Well then. Since you say you have no friends what phone do you have today?
Obvious troll post but I'll entertain.
Perhaps instead of caring so much about what processor is in your mobile device you go out and make friends and then you'll have a use for a phone...
hahahah lol, if only it were that easy!
I bought the iPhone 5S, played with it for 7 months, using SIRI a bit, she was off many times, used the weather app some but that got old. Played with the GPS a little but my car has one built in, and the screen was too small on the iPhone. .
Get an iPhone and download OkCupid.
But seriously, I'm the world's biggest introvert, and I love my iPhone. It doesn't matter if you have a lot of friends; what matters is how you plan on using it. (And for the record, I have met friends through the OkCupid app. )
I have that 520. Bought it for $10 new and used it for a month to test T-mobile service. I made new friends that month as well. You'll do fine.
Get it off contract and don't get cell/data plan.
I hear you can make new friends on Tinder.
