How to know if someone blocked you off their iphone?

My friend and I got into fight the other day, and ever since then I've been texting him but I never got a reply. When I send it, it says it's been "delivered." So I'm not sure if he blocked me or is he just plain ignoring me? I called him a few times too and it would ring a couple times. Just curious to know if ever got my messages or not?

My iPhone suddenly doesn't have any pictures on it! What happened?

My iPhone suddenly doesn't have any pictures on it! What happened?

Added (1). Forgot to add details…

Just the other day I hooked it up to my computer - and all the pictures were there. Unfortunately I was tired and dropped it this morning, and the screen is too cracked now to use the bottom part of it - and therefore I can't type my password since it has numbers in it. I was going to do a phone restore - so I plugged in my phone to backup my pictures…

But suddenly there are no pictures! What in the world happened? How did dropping my phone effect my pictures?

Does my iPhone just need a screen replacement?

I dropped my iPhone 5c a few times, and in the morning i discovered the screen was unresponsive. The screen is a pale black, the backlight. There are no images. Does this just need a screen replacement, or is there something more?

I can't add a gmail email account to my iPhone?

I'm trying to add a gmail account to my iPhone. Since Google is one of the predefined services that appears when beginning the process of adding a new email account, I assume that Apple allows gmail accounts. But when I try to add the account, I get an incorrect username or password error. I have logged into my gmail account on my computer to ensure that I was entering the correct password. So, since I CAN log into my gmail account on my computer, why can't I add it as an account on my iPhone? Thanks in advance for any help!I can t add a gmail email account to my iPhone

Iphone only turns on when plugged in?

Hi, I dropped my iphone 3gs (ios 6.1.6, jailbroken). Since it turned on twice but never went passed the apple logo, then I tried plugging it in to the wall, and it turned on once and went to the home screen and was fully functionnal, but as I unplugged it it went straight back off. I have tried plugging it into Itunes, at first it doesn't recognize it, but if I put it into DFU mode it recognizes an Iphone in recovery mode. I have also tried restoring many times (with ireb, with a custom firmware from snowbreeze) but everytime I get different errors (1602, 3194.). Now, when I plug it into the wall it seems to be in a boot loop, it doesn't go to the home screen, and everytime I look it is either on the apple logo, or black and is turning back on again. And still turns straight off when I unplug from wall.
Please, any help would be much appreciated. I'm dying to use my phone!
