How to save all my pics from my iphone 4 to my computer?

I have upgraded my phone and am giving my old iphone 4 to a friend. I don't know how to transfer my contacts so I will have to write them down, delete, then enter them into my new phone. But unless I text every single pic and video from that phone to my new phone, I don't know how to transfer them. Pics that I have taken from my phone are already on my computer but pics I have saved from a text, or saved off a web site I don't know how to transfer from my phone to the computer. The music I will just have to put on the new phone cause it doesn't have itunes so I can't transfer all my itunes music to the new phone. The pics are my main concern though.

How to reset or clear off a iphone 4?

I upgraded my phone and am giving my old iphone 4 to a friend of mine but I want to clear EVERYTHING off before hand. I don't know how to reset, restore to factory settings, or clear it, how ever you would label it. Yes I know how to remove my apps, therefore removing anything to do them.

So how do you go about wiping it clean or restoring it to a blank phone?

Forgot my iphone 4 passcode

Me and my boyfriend were messing with eachother today and I changed the passcode on his iphone (we both know eachothers codes.)

I'm very frustrated, I don't want to restore it and have All of my files etc.deleted! Is there any way that I can unlock it without having all of my stuff deleted?

How to Set my iphone 4s to automatically use dock connection?

So here is the problem,

I have an iphone 4s not upgraded to ios 6 software. When i connect it to my car stereo that has built in bluetooth, my phone takes 30-45 seconds to connect usually (which is long… ) but the issue is that when i sit down into my car and use the usb plug and plug it in to the stereo music starts playing but then 30 seconds later when my bluetooth connects it switches my phone to bluetooth mode to play music instead of dock connection. So i want my phone to not switch to bluetooth mode for music but still have my phone connect for calling. The problem is when it switches i have to manually hit a button on my phone to make it use dock connection now and its just a pain… Any advice on how to change a setting on my phone to not switch on me?
