Should I stay with the phone I have or get iPhone 5?

I have a wild fire s and it's really small for and android. And it's fat and it's slow
And ontop of that, I have metro pcs for service. It's terrible, I'll send a text and it won't really send until the next day or some one will text me and I'll get it 1 Maby 2 days later. Should I stay with this phone until iPhone 6 or get the iPhone 5 now. Or any other phone recommendations if so, pricess?

If I were you ( and could afford it) I would get an iPhone 5

I would get the iPhone 5. Sorry, no offense, but it sounds like your phone sucks so I definitely wouldn't wait another year for another iPhone to come out.

I'm an iphone 4S user and I think you should skip the Iphone 5 and either wait 1-2 months for a new Samsung to be released (usually end up being faster, more powerful, and with more cool stuff), or buy the current Galaxy S3.

If you really have to get an iphone, then go with the 5, but it has almost no difference with the 4S. Apple is being slow at innovating, and seems to be trying to catch up to Samsung instead of taking the lead.
