I have some questions about Iphone 4?

[Mango]

1. Locked phones can still go on web, download apps, and play games.
2. That's not true. And Apple doesn't sell the iPhone 3GS anymore.
3. iMovie, iPhoto, and Garageband are really necessary, but they're fun to have. Definitely get Find my iPhone (if you lose your iPhone), and Find My Friends. Also get Instagram (adds cool, vintage effects to photos), iTunes Movie Trailers is great, Pandora radio, Soundhound (if you hear a song playing and you want to know what it is). As for games, I like Cut the Rope, Angry Birds, Words with Friends, Plants vs. Zombies, Doodle Jump, and Infinity Blade and/or Infinity Blade II.
4. If you can afford the 32GB, definitely get it. Just know that you can't get the iPhone 4 or iPhone 4S with 32GB of storage. If you want 32GB, you have to get an iPhone 5 for $299.

I hope this helps -- congrats on your new phone
