Can you copy music from one iPhone to another?

My boyfriend has an iPhone 4 and just bought me an iPhone 4s, him and I have damn near the same exact taste in music. I need to know if there's any way to COPY the music that is on his phone and put it on my phone without him losing the music. I'm afraid if we transfer it that he will lose the music from his phone and it will all be on mine, which is not the goal. We want the music on BOTH phones. Is there any hope?

Is it worth getting an iPad mini or should I get a iPhone 5?

I mean apple is a brilliant brand but they have one flaw they are constantly outdating their product like the iPad mini came out recently and apparently in the first week apple reported that they were working on the iPad mini 2
So is it really worth getting an iPad mini if it is just going to be outdated in a few months or should I just get an iPhone 5

Videos

Ps don't take money into consideration it is not a problem the choice is iPad mini or iPhone don't sujest anything else

Is 40GB internet allowance per month enough for my household?

In my house we have two laptops and two iPhones which are connected to the BT Home Hub. My brother and I browse the internet, we don't download games and rarely download applications (unless it's from the apple app store for my MacBook). Our browsing is quite heavy-use though. I'd say I spend around an hour every night on my laptop, and my brother spends around four hours.

WIll 40GB be enough?

Why can't I send picture messages to people who don't have iphones?

I have an iPhone 4 and whenever I try to send pics to ppl who don't have an iphone, it fails. I have data on, 3G on SMS on and MMS messaging on and they still don't send. The pictures are also not in HDR when I take them. Is it because some people who I'm sending them to don't have smartphones? I have everything on that's supposed to be on so I don't understand why they won't send.
