How to drag and drop music onto iPhone?

So I attached my iPhone into my computer and I would like to drag and drop music from this computer into the iPhone. I have done this action before, but on a DIFFERENT computer. I know that you are supposed to select the "manually manage music and videos" option, but then it asks if I would like to "erase this iPhone and sync with this iTunes Library." I do not want to loose my music just to add a few songs from this computer onto my phone. Is there any way possible to fix and allow me to drag-and-drop from this computer?

Installing Apple software on a Windows computer?

Alright so I have an interest in creating apps for the iPhone but for some reason Apple doesn't want to allow development on Windows computers (I completely understand the competition reason but not everyone can afford a Mac).
So I have been Googling around and have found that it is possible to run Mac software on my laptop but I'm kind of confused as to what it does. I know that it probably isn't legal but I'm not asking someone to tell me how to do it all I want to know is what it does and if it's safe to do because my computer is also used for school and I have Microsoft Office and all of my school stuff on here which I would prefer not to lose!
Thanks

Added (1). I can do it lol I have the expertise and I understand the no support thing. It's hard for a college student to get the money for those expensive things!

I love the show courage a lot, one day I was on the iPhone app "ifunny" and it showed a picture of the episode "The great fusilli" with courage holding Eustace and Murial like puppets and it reads "This shows that Eustace and Murial are actually dead, and courage went insane and actually makes them think like there alive, and he also made us think that there alive"
I ask you

How to get the most possible money out of selling an iPhone on eBay?

I have an iPhone 4 8GB (White) on Verizon, and I'm looking to get the new iPhone 5.To get the money, I'm going to sell my iPhone 4 on eBay. First of all, I have the original packaging, headphones, and original charger. I will make sure that the phone is completely wiped down and clean, and I'm going to throw in my $30 Otter Box to sweeten the deal. The phone is in very good condition. I will also make sure that the phone is restored. The point of my question is this: I've heard that if an iPhone is unlocked and/or jailbroken, it will go for much more money. Is this true? And I know nothing about how to unlock a phone. I do know how to jailbreak it, however. Would you advise me to do this? And how do I unlock an iPhone 4 on Verizon? Thanks!

-John

p.s. How much should I hope to get for it?
