IPhone 4 to StraightTalk

I'm trading in my HTC Inspire 4G for an iPhone 4. I currently use StraightTalk as my carrier, and would like to do the same with the iPhone. But I don't know what all I would need to do that. Do I need to purchase a sims card from StraightTalk? And would the iPhone need to be unlocked? I'm totally clueless!

How to unjailbreak an iphone WITHOUT losing music?

I jailbroke my iphone a long time ago and now I can't add or remove music from the device due to some problem with the jailbreak. All of the music that is on there now is not on my computer so if it is deleted it is gone for good. The music isn't linked to my itunes account either.

Also I should note that when I plug my iphone into a computer itunes or any other program does not recognize it. The only thing that pops up is the folder that contains pictures stored on my device.

Is there any way I can unjailbreak this thing without losing my music? Maybe an app from cydia or the app store that will back it up or something. I dunno.

How to get a Saints Row III online pass?

I bought a new game at gamestop "Saints Row: The Third" as a Pre-Owned. I never heard of a console game needing a online pass but apparently you need a online pass to play online. Even though I pay an high price EVERY month to renew my Xbox Live, They actually think i'm going to pay more for online. Online mode has already gotten me enough financial problems. Its just a scam to get people to buy new games because the new game money goes directly to the developers. What I want to know is how do I get a Xbox 360 Saints Row the Third online pass online for free. It can't be a download because i only have a iphone.

Does the genius bar cost money?

My iPhone 4s, out of warranty, has just randomly shut off and it will not turn back on. I have plugged it in and done anything and everything possible. The lock button is also messed up, so I can't do the reboot thing. No one has been able to help me, so I decided to reserve a spot on the genius bar thing on the website. Then, I saw that they charge certain people. Will they charge me for any services? I do not have any money to spend at the moment.
