1. Facebook
Assuming you have a Facebook account, you’d quite literally be insane not to have this app. Watch your news feed, send messages, upload photos, stalk that individual you so dearly desire… o.o
2. Dropbox
Dump the files you want to sync in a folder on your computer, and your device will allow you to access them, download them, and even view them.
3. Skype
Allows you to use Skype on the go! Though a little finicky and annoying, it’s still a good download if you are a heavy skype user.
4. iBooks
iBooks is a great all around app, it allows you to read ebooks and pdfs on your iPhone, and it even allows you to upload your own pdfs, such as formula sheets and manga!
…is that lame?
If you like iBooks, check out the Kindle app!
5. Wikipanion
An iPhone app dedicated to providing a seamless Wikipedia browsing experience, ad free!

8. Shazam

I thought about leaving this one out because it costs money, but I think that this app is especially important. Having saved numerous lives before, this app gives you hundreds of pages and videos that you can easily access in an emergency to save a life. CPR, seizures, cuts, wounds and more.
