I want to return my iphone 5?

I upgraded my phone today to a iphone 5. I went to the T-mobile store to upgrade (in the UK). But I've been having a lot of problems with it. The reception is really poor at my house compared to my old phone and the screen is really unresponsive. I have to tap the screen about ten times sometimes before something happens! Also as a side note, the more I use the phone, the more I realise I hate the interface on the iphone and really prefer the android interface.

Would I be able to return this phone? I read elsewhere online that only phones bought online can be returned within 7 days, but not phones bought in store? Any advice?

I don't feel confident with glasses

I'm in high school and i have glasses. I've been wearing my glasses my whole life and i always wished that one day i would wake up and be normal without glasses, with an iphone and so on… But i feel so lame because i look like a nerd without a smartphone and i'm shy. So i just moved to a new high school, 9th grade and no one is wearing glasses and i feel so akward. I have contacts but my mom doesn't have enough money to buy them for me all the time. I need some tips how to feel confident again.

How to remove the phising scam Rasberry Ultra drops?

My dad recently got attacked by the new Rasberry Ultra Drops scam. All of his contacts in his e-mails received the link. I received the link but quickly dismissed the e-mail because I knew that was a scam. My dad doesn't have a Face Book so thats great. But I wonder, how could we stop the phising virus from sending fake messages? I told my dad to change his gmail password but he said that won't work. He only uses his macbook air and ipad and his Iphone to send e-mails. Any help?

Acer Aspire won't load up USB flash drive?

I've been trying to do something with a flash drive with my laptop but it isn't working. At first I thought it was the program's fault but after using the same program the same way on another computer I learned it wasn't. Basically I inject the USB, the light blinks, but then I can't load it up. I've tried the USB Root port delete thing and it still didn't work. The computer is an Acer Aspire 4011. I hook up my iPhone charger to it a lot too and the computer easily detects that. And to be clear, I'm not getting an error that the flash drive is not loaded, it just doesn't show up. Anyone know if there would be a setting or something that would do this?

How to prevent my iPhone photos from being accessed via USB?

I don't want my friend going through my iPhone pictures. I just tried an experiement. I set my phone to "lock immediately" and tried connecting the iphone to my laptop via USB. I could still access my photos even thought my phone was locked! Isn't this a huge security issue? Tried googling to find a solution and didn't find much. The second experiment I tried was sneakily connecting my friend's locked iPhone to my laptop to see if I could access his pictures. Even though his phone was locked, I could NOT access his pictures on my laptop. I'm sure that he actually has pictures on his phone. My friend is very knowledgeable about computers and it's obvious he's encrypting his phone somehow so that his pictures can't be accessed. Can someone explain how I encrypt my phone so that it can't be accessed via USB? (pictures, videos, files, etc.)
