If someone knows your IEMI number, is it a bad thing?

I'm selling an iPhone on eBay. I've given the model number and plenty of pictures. I bought it straight from the Verizon store and it hasn't been opened, I told them all that. But people keep asking for the IEMI number. I was able to look the number up, but I read it uniquely identifies the phone. Should I give it to them? Is is possible these people are not trustworthy and will use the IEMI number for crime/scams?

I dropped my Iphone 5 in water, should i be worried?

So i was washing my hands and my phone fell into the sink while the water was still running. The phone wasn't submerged but it got wet. I turned it off immediately and threw it in a bag of rice just for precaution. Should i be worried considering the phone was never submerged and leave it in the bag or am i freaking out over nothing and my phone is fine?

Iphone 4S can't locate Wi-Fi networks?

I had Wi-Fi and full internet connection this morning, less that 12 hours ago. I went to college, and my phone couldn't find any network connections. I thought it was just the library Wi-Fi being a bit crap so i thought nothing of it. Then I went home where my phone automatically connects to the Wi-Fi but I still had no signal. My mum and sister both had full Wi-Fi and internet access so, Yes my internet router was on and working.

But no matter what I try it just can't fund any available internet connections, usually I can pick up 2, ours and our neighbours.

Yes, i have tried turning the phone on and off, I've turned the router on and off, I've rebooted my iphone, I've reset my network settings.

Why is radio still prevalent?

People still listen to the radio when it's such an old form of entertainment. I think that's great! These days older things are usually quickly trumped by newer tech, but radio is still around.

It's like iphone 6 replacing iphone 5 soon even though 5 is only a year old. Why is our society so stupid as far as consumerism goes? It's ridiculous.

What's going to happen to my photos on iPhone when I sync it with someone's iTunes?

My friend has a lot of music on her iTunes and I thought that I could sync my iPhone with her library. I know that once I do that all the music on my iPhone will be erased but what will happen to my photos? I tried to back them on my laptop by copying and pasting it but from 3067 photos only 2975 were copied and I selected all four folders.

Anyway, my question is. What will happen to my photos once I sync my iPhone with someone's iTunes Will they be erased?
