How to watch free tv shows and movies on my iPhone?

Can you please tell me how to watch free tv shows like HIMYM, one tree hill, modern family, new girl etc on my iPhone?
I have Wi-Fi too. And it cn be any website or even an app is fine. My phone is NOT jail broken and I don't plan on doing so. Help ME Please!

Added (1). I can't get crackle because my App Store is not the US App Store and so it won't download.

Go on app store & download ITV Player & BBC iPlayer

I'm afraid you will have to jailbreak your phone.sorry
but
if you do the Netflix Free trial for 30 days you can watch instantly from your iPhone
Sorry )

You can find full length movies on youtube.com
either type in Crackle or movies or full length movies and you will get results.
i recommend Crackle

they may not be the movie you are looking for, but youtube does have a pretty good selection, and they are free.

The options will depend on where you are so as to comply with the local licencing arrangements.
