How to import photos and videos from my iPhone 4 to my computer?

My PC uses Windows 7. I have tried the official instructions from Apple, however when I go to Start->Computer, my device does NOT show up as it says it should.

Here are the instructions from Apple:
To import photos or video from your device to Windows:
1.Connect your iOS device to the computer. If the AutoPlay window appears, click "Import Pictures and Videos using Windows", then skip to step 4. If the "Import Pictures and Video" dialog appears, skip to step 4.
Note: If the AutoPlay dialog box does not automatically open, you may need to enable the behavior
2.2.Choose Start > Computer.
3.Right-click the logo for your device and click Import pictures and videos.

I can't seem to do Step 3, as there's no logo for my device or option to import pictures.

Any help would be appreciated!

a. State the population distribution (that is, the probability
distribution of X for each observation).

b. Find the mean of the sampling distribution of the sample
proportion who have the app among the 50 people.

c. Find the standard deviation of the sampling distribution
of the sample proportion who have the app among
the 50 people.

What happens if I update my jailbroken iPhone?

So it's pretty straight forward, I jailbroke my iPhone 4S (iOS 6.1 evasi0n untethered jailbreak) and the only thing I'm still not sure about is what happens if I update to let's say iOS 6.2?
Do I need to restore with 6.1 first? Do I just update? Will I be stuck with 6.1 because apple won't be signing 6.1 anymore?

I know I lose the jailbreak when I update I'm just uncertain how I do it.

I want to cut my sim card into a micro card for iPhone 4?

I'm currently on a £15 month contract on vodafone where I get unlimited texts, 300 minutes and 500MB of internet. Because my current phone isn't working I'm going to buy an unlocked iPhone 4, I don't want to pay £30+ a month so is it possible to cut my sim card into a micro sim? Will this work? And will I be able to still pay £15 a month?
