I dropped my iPhone 5 and now it has a few scratches on the screen

Any suggestions on how to remove them? ( if its possible ) I always have been very careful when it comes to technology, especially mine, and it kinda made me sad when I dropped it accidentally on the floor, landing on its screen. Would the stuffs in the phone be damaged even though the screen isn't cracked?

My instagram is crashing still

I have been trying to contact the help center for Instagram because its been crashing for the past 3 weeks. I have contacted my service provider, reinstalled the app, gave my iPhone 4s a soft restart, EVERYTHING! And still no luck. Instagram help center will not contact me back and I have been buggin them for weeks. I'm on the verge of just deleting the app because at this pointl its just pointless. I made another page but that page began crashing as well, so I must be the version which is 3.5.1. Has anyone else had this problem and resolved it? If so please give me some tips, its just aggrivating. Instagram has money, THEY CAN FIX IT! ALSO I updated my iOS to the latest version 6.1.3 (if they helps any)… Help ME Please!

Why i can't open allkpop website on iphone?

Allkpop recently change their website format. I would usually check kpop information on allkpop through twitter but ever since they change their format, my twitter could not open their website to see what a post would be about. May i know how i should solve this?

Oh and I would open allkpop website on my safari, this would pop out: unfortunately the full features of the site will not function if AD BLOCK is enable - features such as the Music Player, earning of Activity Points, Navigation and more. In order to enjoy the full experience of allkpop, please disable AD BLOCK.
But i don't know what is ad block and i don't have it in my phone, so please help me

What do i do if my iPhone won't charge due to water damage?

I had a glass of water beside my bed and i was using my phone in bed with the charger plugged in. Then i took the charger out and it was just lying beside me on the bed.later on i must have pushed it off the bed and it landed in my drink. I didn't notice for around another hour. I had 7% battery left and i wanted to charge it overnight for school the next day so i dried the 30 pin dot connector (or so i thought) and charged my phone. I woke up the following morning to find that my phone was only on 60%. I then took out the charger from my phone and noticed that it was mouldy.later in the day i noticed some mould in my phone. My mum/mam/mom (whatever you wanna call it), cleaned them with a toothbrush but it didn't work. It got rid of the mould from the phone but the charger was rusted.today she bought me a new charger and it didn't work. My phone is dead and won't charge. It worked as normal when it was charged.

Is there anything i can do? Will i need to have it repaired? I'm not gonna take my phone apart because i'll end up breaking it and i will only trust a professional with it.

I still have the receipt for the phone. Does that automatically give me a warranty or do i have to buy a warranty when i buy the phone? I bought in October and it's now May.

External hard drive for lap top?

I've got a laptop that is fairly old, I pretty much use it only to sync music with my iPhone, I like to keep all my best albums stored on the laptops memory so when I come to change the music on my phone its a quick 5 min job of syncing the new albums, the problem is having all the music (I've got a lot if CDs) stored on my lap top makes it run unbearably slow, also I don't want to have to rip a cd each time I want to put it in my iPhones music, witch I change quite a lot,
I've been thinking about getting an external hard drive to store iTunes and the large amount of albums I like to keep on tap.
I don't know much about pcs laptops ect so not to sure what to get, size wise about 250gb would be good I also want something that is easy, something i could just drag and drop my iTunes and its music straight to the external hard drive and free up space on my lap top, also nice and easy to put music from the external hdd to my iPhone, also I don't want to pay too much money I've tried searching on eBay but I just get a list of cables, I thought external hdd plugged in via USB? I'd really appreciate it if some one who knew the part that would help me out could find one eBay and leave the link for that auction in their answer, also pretty standard, I like things as cheap as possible!
Cheers

Which is better in these situations?

Iphone 3gs 32 GB or iphone 4 16 GB.

I know I phone 4 processor and ram speed is better but, i think the high screen resolution will reduce the speed
