IPhone 4 auto play won't work?

It would always work, now for some reason it won't.
I can't even find it on the "Computer" section.
I even put, "always pop up", "always auto play" whatever it says.

I have iOS 5.1.1,
I have no space because of how many pictures I have, 12k, don't ask.
Anyways, I want to save my pictures so I have enough room to update.

Anyone know what to do?
This has been going on for almost a month now.
Only iTunes can pick up on it, but that won't help because of the pictures.
(I want them on my PC)

Iphone importing of contacts problem

I have a Apple Iphone 4 which used to be my older brother's. When I imported my contacts from my sim card, after resetting the phone, it also imported my brother's contacts as well even though I'm using my sim card and he has his. I would like to only import my contacts and I'm finding this rather annoying.

How to get rid of the other category in my iPhone's usage

The "other" section is currently taking up 7.5GB of my iPhone's capacity (so ridiculous)! I've tried everything: deleting contacts, deleting conversations, deleting apps, and even RESTORING MY IPHONE. But it still is taking up basically half of my usage! Please someone tell me how I can get rid of, or at least drastically reduce, the "other" section.

I Can't find my app store

I recently got a new Iphone 3. I have downloaded a few apps, such as facebook, instagram, and piano. Anyway, i was going to download more apps- but there was NO app logo! I assumed that maybe it went in a folder perhaps? No. Perhaps i could search it and it would come up? No. I tried this with my other apps like Pandora, and when i searched it, it popped right up! And I know that sometimes, if you search an app, you can download it through the app store website, well- thats not working either! Please help! I would like some apps for Christmas but my phone is NOT agreeing with me! And its not like I can just download the app store!
