I didn't actually use this one, because I already had a care kit. But I am sure any eye glasses care kit will do. Use the spray and the cloth to clean the iPhone thoroughly before you put any of the screen protectors on it. Otherwise there will be bumps and air bubbles.

The best head phones I have come across. Color doesn't matter. They fit well. Not so sure about the microphone yet, but every blog I read said that these were the best.

It's easy to get on. Good grip. And I feel like my iPhone is protected. Which I guess is what I need. I don't know if I ever trust any of these things to keep it safe from a fall, but peace of mind is nice. I like how it protects the buttons, comes with two screens (as it took me forever to get it right... should have cleaned it the first time), and it comes with a plug for my connector area.

Any of the bundles are good. The cases probably won't be great, but if you feel like changing the color to match your outfit... I get them more for the extra chargers. I like to have lots. One at the office, purse, in the car, suitcase, home... And it's so much cheaper than getting one at the apple store. They retract which is nice. And plus you get extra screen protectors!
