Just wondering, I dont want it to happen to me, that stuffs freaky.

It would only be possible if the iPhone you were trying to hack was already jailbroken.

For my birthday I received around $50 worth of iTunes cards (To be totally honest, I use apps more than the phone itself!). However, I am unsure as to what I should spend my credit on. Therefore, I am looking for an open-world sandbox game for the iPhone. Any ideas? (Top-quality games of other 'genres' will be accepted as well). P.S. I already own the following: Ravensword, Crusade of Destiny, GTA III, Gangstar Rio City of Saints and 4×4 Jam.

What about Grand Theft Auto 3 Tenth Anniversary Edition? That is a really awesome open world game.
Gangstar West Coast Hustle and Miami Vindication and Gangstar Rio?
Infinity Blade 1 and 2
Other non open world but seriously fun games are

9mm
Max Payne Mobile
Modern Combat 2 and 3
N.O.V.A 2 and the upcoming 3

I downloaded a song from YouTube and transferred it to my iPhone, now how do I set it as a ringtone?
I can play the song on my iPhone but can't seem to set it as a ringtone.

You need to make the file into an .m4r file in order to use it as a ringtone. Easiest way to do that is to make it an .m4a file in iTunes (use the Convert to AAC option), then rename the file (change the .m4a to .m4r), then put it back into iTunes and sync it to your phone.

Yes, it's a pain. Blame Apple.

I wanted to get a new phone. The phone MUST have instagram, twitter, & facebook in the app store/market. I have MetroPcs. Any good phones that have those apps? Or should i just get and iPhone 4s? Is it true the Straight talk plan on AT&T is $45 And is unlimited?

Get the Samsung Galaxy S2. It does everything (and more) than the iPhone 4s and will be a lot cheaper. Instagram is now on the android market, as is twitter and facebook.

I want to buy a ringtone on iTunes, but I have an iPod not iPhone. I just want to know, if I buy it, will it work on the text free app?

I don't think it would, as iPods are not set up to handle ringtones
