Lost iPhone with no passcode, should I be worried?

My iphone was stolen in Mexico yesterday and didn't have a passcode. When I still had the phone I tried using it in free Wi-Fi areas but still didn't work (there's hardly any free Wi-Fi there).

I tried locking the phone through icloud but I guess "Find my iphone" wasn't installed in my phone.
I also blocked the line but should I be worried of them getting into my signed in social media accounts and emails since Wi-Fi didn't seem to be working in the first place?

Call the police and tell them this they will investigate

Sure, the first thing the thief is interrested in is YOUR stupid facebook.

  • Should I be worried that my iPhone has been compromised? After browsing the web for about half an hour or so I get a pop up saying that someone is trying to access my iPhone and that I should get rid of all the viruses. It states the persons ip and the location which is the Ukraine. Is this some sort of scam because I've heard that iPhones can't get malware because you're not allowed to download anything from the web. So my question is should I be worried.
  • Should i be worried about my iphone 5? I've had this iphone5 for a month now and i've only noticed now that there's a red glowing dot near the top speaker. It can only be seen in the dark. After doing some research i think its supposed to be the proximity sensor but some people say its abnormal to be seeing this? Is this a problem? Should i be worried? What's a proximity sensor anyways and how do i turn off the red dot if possible?
  • Should I be worried about my iPhone 4S? It got wet in the rain and now the speaker is not working. Not sound is coming out of it in any way. It's all still functioning fine apart from that. I'm hoping it will dry out and start working again.
  • IPhone 6 has a hole poked in the speaker mesh. Should I be worried about it or not? Not a big hole. But I'm worried water or something could get in. Can you get a replacement for the loudspeaker mesh too?
