Saving iPhone 4 Photos To PC?

I have the iPhone 4 and in the beginning whenever i connected it to my laptop, went to the folder, clicked copy and then pasted to 'My Pictures' then the photos i copied and pasted from the folder on the phone would be saved onto a folder on my laptop. Now when i do it not even half the photos get copied even though i have them all selected. What is wrong and how can i fix this problem? It's like it only copies some which doesn't make any sense.

Can't unlock passcode lock iphone 5?

Hey ok i'm pretty screwed over here but ill ask for your help.
last night i was out with some friends and droped iphone 5 and accidently ran over it!
well i was lucky and had it in an otterbox but my touchscreen dosent work
i've been having siri do everything for me like place calls.
but here is my question,
My iphone touch screen does not work, i have a passcode lock on iphone,
is there a way to unlock iphone through my computer
or what to do

Added (1). I can still use my phone to place calls. But i can't check my missed calls without my phone being unlocked, and i can't answer the phone cause touch screen doesn't work so if i can get my phone to shut off passvode lock then i can have siri access everything on my phone for the most part.
