Should I trade my IPhone 4 for a Samsung Galaxy S2?

Which do you think is better? I like to use my phone for everything! Pictures, videos, video chat, homework, movies, social networking, etc. Which is better and why!

If your iPhone is doing everything you want to do… Then don't trade it. A Samsung Galaxy S2 is not a good phone and the build quality is terrible. If you wanted to trade, it should be to the new iPhone 5 or the 4S only because all your iCloud stuff is on there.
