Is iphone video downloader safe to use?

I downloaded "video downloader" From App Store. It allows you to download any video you want, while safari doesn't let you download them. So can I get any viruses by downloading any videos with this app? My iPhone 4s isn't jailbroken.

How to get my iPhone 4s to connect to Wi-Fi?

I have an iPhone 4s (iOS 8.0.2) and it won't connect to Wi-Fi. It actually does "connect" like it will show it in the Wi-Fi section in settings and at the top of my phone, but it won't actually register that it has Wi-Fi. I tried to use my 4g and the same problem. Recently, I had used my personal hotspot and connected 3 devices. If anyone has anything please let me know!

Problems adding credit card to Passbook on iphone 6?

How would I send information through different types of users through the use of databases?

So I want to make either a website or iPhone app and it will have 3 different types of users that all have different functions. I'll refer to these as user 1, user 2, and user 3. The lowest user, user 1, should be able to either take or upload a picture and send it with comments to user 2. My question is what would be the best way to implement this? How difficult would it be to do this with PHP for a web based application vs using Apple's Swift language for an iPhone app?

As for the database part, I know the app would require a database, but how would that integrate with the sending of info back and forth between the different user types?

Also, if I'm working with PHP, what would be the best way to go about creating the 3 different users with a login system? Are there any existing frameworks or tools out there that would do this for me, because I read that by doing it yourself you are bound to leave security holes open which would make it insecure.

I got the iphone 6 11 days ago and it won't turn on?

I got the iphone 6 11 days ago and it won't turn on. When I plugged it in last night it said it was charging but now there's no response. It seems like it's dead and there's nothing I can do to turn it on. I tried holding home and the on/off button, I tried plugging it into my lap top while holding the home button and just holding the on/off button, nothing seems to work.

Should I download iOS 8.1 on my iPhone 5S?

I've read a few reviews, and some of them say that their phone is slower now that they've downloaded iOS 8.1. Has anyone else experienced this? Apart from speed, what are the other positive and negative points of downloading it? I'm probably going to wait a couple of weeks anyway, so there's time for people to find all the bugs, but I just wanted an idea of what it's like.
