How do I restore Apps to my iPhone 4?

So, I plugged my iPhone 4 into my computer last night, before I went to bed for the upgrade. When I woke up this morning, the upgrade was finished, but none of my app's were on my phone.

Even more bizzare: All of my texts, photos, and music is still on my iPhone, but none of my apps are.

I backed up my phone before I made the upgrade.

Is there a way I can get all of my apps back? I paid for some, and others have months and months of history on them.

Any ideas?

Ok, so I plugged in my iPhone and went to the Apps tab. There are no apps for me to sync or no options that I can find... grr!! Help!
