What's the best Advanced Learner's English dictionary as an iPhone 5c app?

Since I'm planning to spend money on this dictionary, I'm expecting these features:
1. Tenses for verbs (must be included)
2. Plural form for nouns (must be included)
3. Off-line pronunciation ("Off-line" is optional, but pronunciation must be included. And I hope it's not so robotic.)
4. Examples for different meanings (must)

I found these available on my iTunes:
Cambridge Advanced Learner's Dictionary $15.99 Audio version is $21.99
Collins COBUILD Advanced Dictionary (6th edition, 2009) $9.9
Longman Dictionary of Contemporary English 9.99
Oxford Advanced Learner's Dictionary $30.99

I use Collins COBUILD on my computer. I'm very happy with Collins, but I'm not sure if the app is as good as the computer version. Please help me out. Any advice will be appreciated.

Added (1). Fuzzy search is also a great feature. Tell me about your experience with these dictionary apps.

Can I update my iPhone without backing up my camera roll?

So if you go on your iPhone to Settings>General>Usage>Manage Storage>This iPhone(which is the phone I'm using) it shows my backup information for my iPhone. I don't have anything backed up (in the picture) because it takes up way too much space on my phone. Is it possible for me to update my phone to the newest iOS without losing all of my pictures? I'm not sure how iCloud works even though I have had it for years but please help! I need to update my phone but I don't want to lose my pictures or contacts or anything.Can I update my iPhone without backing up my camera roll

Where can i buy a cheap unlocked iPhone without a contract?

Where can I buy a (cheap!) unlocked iPhone without a contract? I know you can buy them from the apple store, but $749 is way more than I want to pay.

I basically want to use the phone as an iPod (like with Wi-Fi and stuff), but also be able to use it with a contract someday.

I know someone who uses their old iPhone like that- so can I buy one off ebay or something?

How to organize photos on iPhone?

Apple is amazing at everything, except organizing photos, especially on phone or iPad.

the photo app has 2 buttons at the bottom, albums, and photos. And the photo section is a horrible jumbled mess. So tell me, how do you organize your photos on iPhone.

what happens is ill take photos at, lets say a birthday party. They'll be in the camera roll under photos, but i want them in they're own separate spot.

on the photos side, where it organizes everything by location and date, it will put those photos aside, and call them something like, "1234 somewhere ave. Lakewood Michigan" well, i want it to say, mark's b-day, not an address.

then there will be those random photos. Like, you see something at the store you want for christmas, so you snap a photo of it. Your at best buy and your comparing prices with another store so you snap a photo of the price tag. All those photos, great to be put in the camera roll, but when you look at the photos section, a christmas present and a price tag are jumbled in with the birthday party and the time you went to the park.

so how do you organize that?

and then i have a separate camera, and importing those photos; i could ramble on forever about that.

ITunes won't transfer music to my iPhone 5?

I'm using the same computer, phone, etc. That I have been for 2 years but all of a sudden iTunes refuses to transfer music to my iphone. It either 1. Says "iTunes can't add any songs to the iPhone because no songs in your iTunes library can be copied to this iPhone", or it will say "preparing to update" and act like it's about to put the music on, but it just gets stuck on preparing to update and just stays like that and doesn't actually transfer the music. It's frustrating. I don't know what I could have done to make it do this. I also just updated both my iphone and itunes to the latest softward but this problem has happened before I did that and is still happening now. I tried turning my phone off for a while and back on (that seems to fix a lot of things) but it didn't work. What do I do?

Added (1). Oh and I use the "autofill" button but this also happens when I try the "add to" button and try to add specific things.
