Synching iPhone to New Computer?

I just got a new MacBook. When I tried to synch my music from my iPhone, it said that since the iPhone can only be linked to one iTunes account at a time, that it will erase all music from my phone and replace it with the music on my computer (which is none because it is new). How can I get the music from my phone to my computer without having to erase everything from my phone currently?

I accidentally messages my crush and this is his respond

2 months ago on Facebook I mistakenly messages my crush and told him sorry wrong person. We talked a lot in the beginning of last month so you would have to scroll pretty far up to see they message I sent to him by accident. Anyway my cousin took my iPhone and went on my Facebook and messages him instead the of the person that was on top if him on the message list and she said sorry wrong person. Then he messages me you seem to mistakenly message me a lot. After I explained what happened with my cousin he said oh ok lol. What did it mean when he said you seem to mistakenly message my a lot.

Phone to buy next, iPhone, Nexus?

Currently have an Xperia S although is starting to feel a bit old and am due an upgrade, although i'm going sim only next due to the cheaper cost and better data allowance which i need!

So will be buying a new phone, I don't want to spend anything over £200 so will be looking at a used but very good condition phone.

Id love a new iPhone but too expensive, a 4s might be just in budget but would rather not spend that much! Already have my ipod for music.

All i want in a phone is snapchat, instagram, twitter and a decent camera that isn't slow and dim witted like my xperia s at times, plus no lag if possible!

Is the nexus 4 my best bet, or just get an older iphone?

Added (1). To add, I don't want anything from the Samsung range! Don't get on with them.

Would a 16gb iPhone 5s be enough memory?

So I'm looking to get an iPhone 5s but I don't know whether I should get the 16gb or the 32gb? I would have about 200 songs, a bunch of photos (over time) and a bunch of games, and just normal apps. Which would be better. Oh and I'm 15 by the way and hope to use it for 4-5 years…

Or should I get 32gb?
