What does the cloud icon mean in iPhones App Store? - 1

I recently purchased a new phone which was an iphone 5s. I went to download the Facebook app but there was a cloud with a down arrow in it. I pushed this icon and it starting downloading Facebook again. Is this linked to iCloud? I don't want to use iCloud and have never logged into it. But my brother has it. Does that mean if Facebook is downloaded through iCloud on my phone that it will be downloaded on his and he can go through my Facebook page. We have joint phone accounts. I don't use iCloud as don't want him or anyone else seeing my data on other devices.

Accidentally deleted a note on my iPhone?

I had several notes (if I had to guess around 8-10) on my iPhone. One I accidentally deleted a few days ago. This note was and still is VERY important. I need to know a way to get it back. I don't believe it was backed up onto my icloud account. I need it back As soon as possible and so it is exactly the same as it was when it was mistakenly deleted

How to get the photos off of my iPhone 4s?

I'm extremely desperate to get the photos off of my iPhone. I got the phone this Summer and a few weeks ago, I dropped it and the screen cracked. So, I (stupidly) bought a replacement screen off of Ebay and attempted to fix the phone myself, which lasted about 3 weeks. Today, the phone screen just went black and I can't unlock it or anything. I tried to plug my phone into the computer to connect to iTunes and it said I can't access it unless I unlock the phone, which I can't do because the screen is broken. I'm just going to get a new phone, but, is there any way I can get these photos off my broken phone?

Having an issue with iMessage?

My fiance has been having trouble with his iPhone. He can send iMessages out, but when somebody with an iPhone (including me) writes back it sends as text message. Everybody has iMessage turned on and he does too. What could be the problem?
