AT&T Has a fast service than MetroPCS 4G LTE , I know it is about $100 for "Bad Service" But that service has more coverage and faster than Metro
If you like to customize and change everything and want something with some lag , something that you need to do tons of stuff to , Then that is Android
If you want a device that you can open and just download and use , Without tons of customization with no lag , That is iPhone
I would stay with the iPhone 4S only if , It has a bigger screen and better customization , To do anything with the iDevices , Got to jailbreak it
With android , You can do tons of stuff without even rooting it ,
iOS is closed off / Android is open source (I like both now and then)
Though the plans are different , 450 Minutes , Unlimited Texting , 2 GB of Data (4G or all data depending on phone)
Which is expensive
MetroPCS is $70 for Unlimited 4G

You might want the Connect
Note- Most LG Connects have overheating
Bad battery life
LG Launcher has tons of lag
You will have to learn a lot about android
The Top Phones I would get-
Samsung Galaxy Nexus
iPhone 4S
HTC Radar
HTC One X
LG Connect 4G (Currently)
That was my list and this was the only No Contract one with a decent price
If I could , I would get a iPhone 4S
So Stay with it , Don't sell it bro!
