Can using ear buds mess up my hearing?

I have never liked ones like these: image

But i do like ones like these: image

thats just to give you an idea of what i use, in case effect vary.

but my grandmother told me that there were these hair like thing on the inside of your ear, and listening to loud music to much can basically kill them off, and they don't grow back. I don't want to mess up my hearing, but it seems kinda unrealistic. So would listening to music form these actually mess up my hearing?

I wouldn't say I listen to music loudly, but I do listen loud enough where i can hear what a person says when their trying to talk to me.

How to add a hyperlink to my posts on Pinterest?

When I post things on my account like movies I'd really like to be able to attach a link to a trailer bellow in the description box, I've seen other people do this. I've tried finding trailers on imdb or YouTube, copying the URL, then copying the URL to the description box and all that comes up is a bunch a scrambled letters and numbers, no hyperlink. I've even tried posting it anyway and then pressing on it after its posted but nothing happens

Note: I only go on my account threw my iPhone and I'd really like to keep it that way. I know that what I'm doing would probably work on a computer but for me that's a really big hassle

Ps. I'm pretty technologically challenged so that's what's up with my probably stupid question. If there's a really obvious answer for my question please be kind, I don't know any better

Please please please help help help, thanks

Where can i buy cheap supplies for bling/decoden iphone cases?

I'm looking to start making these iphone cases, but there doesn;t seem to be a lot of online help as to were to buy the supplies. CHEAP wholesale supplies. As in the actual plastic iphone 4/4S cases, (coloured or clear), pearls and rhinestones (in packs of 1000+), charm pieces, glitter etc.
Also preferably within the UK. Or at least cheap postage to the UK.

Does jailbroken iPhone affect having warranty?

I have AT&T, jailbroken iPhone 4s. The mic does not work and i'm assuming it's b/c i dropped the phone a lot. I've been wanting to fix this for awhile, but i was afraid to go to the Apple store b/c the warranty might not work for me since my phone is jailbroken. I heard from someone that warranty does not cover only if it's water damaged. Is that true and does having jailbroken idevice affect having warranty?
