I got a pop up while browsing the Internet on my iphone 6. Scam? Should I be concerned?

So I was browsing the web on my phone and trying to go to youtube. I tried to type in youtube.com, but I accidentally misspelled the URL and it redirected me to a different website. A pop up appeared on my screen that just kept popping back up when I hit "okay" to close it. The pop up basically said that malware has been detected on my phone and my data has been breached. I needed to call a number in order to fix it. IIm certain that this is a scam, but IIm concerned that it may be right about malware being on my phone and my Information being stolen (specifically my debit card # that I use to buy stuff off iTunes). Is it possible the website could ve downloaded a virus on my phone?

Jailbroken iPhone stuck in recovery mode?

Jailbroken iPhone stuck in recovery mode?

Added (1). I jailbroke my iPhone in ios 8 a few months ago, I tried to unjailbreak it today by erasing all content and settings on the iPhone, during the process it just gets stuck on the apple logo screen, and when I put it into recovery mode and try to restore it using iTunes, I get an error 1671.

Why is my iphone charging so quickly?

The charge isn't increasing by 1prcnt rather whenever i check, it jumps from 30prcnt straight to 35prcent?

Also it charges to 100 percent within half an hour, i've never had a phone charge so quickly, is this a good battery or an issue?

Added (1). i think it may be an issue cause the battery dies within 3 hours of straight use as well.

Added (2). yes i was using an ipad air cube charger. Thats probably why, thanks

App store on my iPhone 6 is frozen. How can I unfreeze it?

I went onto the app store and saw there were updates for some of the ones I have.

I went on and it said I had to agree to the terms of service before I could update anything.

I decided to do it later as I always like to look through this stuff before doing anything to understand everything and tapped on cancel.

Now my app store has been frozen on that screen for the last few hours.

I tried leaving it alone thinking maybe letting it sit locked would reset it to the main page of the app store but that hasn't worked.
