Dude! the DRAGONCON app!! Get it now, to reflect on the glory that was. And it will remind you when it's time to update to the glory that shall be. It's really cool-- you can cross-reference by guest, panel/track, day/time, etc. You can choose the events you wish to attend and mark them, and they'll show up on the calendar inside it. I used the thing constantly this year.
Others I use a lot:
YouTube-- they've removed the built-in version in iOS 6, so you have to download it now.
TuneIn Radio is fantastic-- you can record stuff like it was a radio DVR. And there's stuff on it aside from "radio stations"-- for example, you can listen to the opening segment of Chris Matthews' show from the day before, the entire Rachel Maddow Show audio, and the opening segment of the Norman Goldman Show, the Best of the Left Podcast, the audio from Real Time with Bill Maher, the audio from This Week with George S, the audio from Meet the Press, the Solid Verbal football podcast, etc. Your tastes may vary, but there's all kinds of stuff like that-- not necessarily radio shows OR podcasts--that you can get with it.
Square-- a great app that allows you to charge people's credit cards. At the arts festival here last weekend, nearly all the vendors had it.
Justin.TV-- not that great, but allows you to watch live streaming TV, IF someone is streaming it. I've been able to see big football and soccer games I would've otherwise missed using it.
Every year they put out an NCAA Basketball app for the big tournament, which streams ALL the games live for free.
The Twitter app is okay but they constantly change/update it. Infuriating.
The Facebook app has been CRAP for most of its existence. The new version would actually be usable (it's now much faster) except that it randomly doesn't post an entire comment, deletes words, doesn't show all comments, etc etc. I don't know why they can't get this right. It's updated several times in the last month, too.
NetFlix and HBO GO are great if you want to watch streaming movies and shows. I don't use them as much as I figured I would-- I tend to use my phone more than just passively watch it-- but Mira watches NetFlix on it (or on her mom's) every time we go out somewhere.
Messenger is good for using just the instant message feature from Facebook without fooling with the rest of it.
There's a U-Verse app that works great for programming your DVR when you're away from home.
Audible lets you play Audible audiobooks with some really nice playback controls (like the speed of the playback).
Wikipanion lets you quickly and easily look up stuff in Wikipedia. I use this all the time. Much quicker than looking for the page in Safari.
Dropbox-- obvious.
IMDB-- obvious.
ESPN ScoreCenter-- obvious.
ESPN College Football-- lets you track just CFB, ignoring the many lesser sports.
My wife got me to install Chirp and Yelp and HeyTell, but I haven't used them yet.
5-0 Radio is a free police/emergency scanner. Useful at times.
Audiobooks is an app that gives you access to tons of free audiobooks from Librivox.
CamCam lets you watch via your phone whatever is going on in front of your computer's webcam.
Yahoo PremiereLeague tracks the Barclay's Premiership.
Fandango for movies/showtimes/tickets
Trivi.al Free is pure trivia contests with friends or strangers
Pages is the word processing app I use, mostly on my iPad but occasionally on the phone. It automatically updates and saves to iCloud, so it's always backed up on every device.
Find iPhone.
