Can a iphone 4s get malware?

My friend wanted me to jailbreak my phone but i thought about it because i jailbreacked my old phones but i was told its not secure and my friend got a message that he got maleware and he needs to pay a fine? He never paid it and he doesn't think if its a fraud or it was real. But could your phone get maleware with jailbreak/or without. And could it get virus by going on fraud websites and websites you shouldn't see and websites that take credit cards.

Having problems with my iPhone 5 earphones, am I the only one?

2 Christmases ago I got a IPod touch and the earphones for that started to make the music sound like a broken cd within weeks then within 5-6 months they stopped working entirely. Last Xmas I got a iPhone 5 and the earphones that came with that are doing the same thing as the other ones did. I love the earphones made by apple and prefer them to others but they cost £25 for new pair which I can't afford.
Am I the only person who this is happening to? If not, how did you resolve this issue?

Iphone extremely difficult to charge

There are three people in my house with iPhone's and lately they have all become extremely difficult to charge. We all have our own individual chargers. Every time we plug our phones in to charge, they charge for a second and then don't or a message will come up saying that it isn't supported. The same thing happens when the wire is plugged into a laptop. What should we do?
