Iphone 3gs Or Nokia Lumia 620?

Hello i'm a student in school and as far as you know i got a low budget so i was wondering which is the better phone to buy. The iphone 3gs or the nokia lumia 620? If you want to ask me why i want the phone.well i just want it to play games/app and some web browsing on facebook and youtube (i don't want the phone to be laggy though) so please list the better phone in your reply with strong reasons.

Nokia Lumia 620
Everything beats iPhone

Nokia.

Nokia 3gs a piece of ***

Even though the iPhone has more apps, a lot of them (especially games) do not work on iPhone 3GS. The software on the iPhone 3GS is too complex for the older hardware - so it is very slow.

There's Internet Explorer built in, with apps for Facebook, YouTube also, and Xbox handles gaming. I would definitely take the Nokia Lumia 620.
