How long will it take to arrive?

Last night (Sunday night) I ordered an iPhone 4S brand new from apple.com/uk/ 16GB White, I bought it under 24 months Barclays financing, how long roughly will it take to be delivered to my house?

Got a weird voicemail, unknown caller?

In match sometime I got a weird voicemail that I just saw that I had gotten now. Some girl with an English accent saying she knows me from 2nd grade and wanted to hook up. Umm. I never remember a girl with an English accent. The voice sounded like a machine maybe but it sounded really real also. It was unknown so I can't see the number to message back. But in the message she said my name, and the city that I lived in. She said
"hopefully we can hook up given the time that I'm in (the city I live in)" Is there any kind of app or something I can use to find out who it was? I have an iPhone 4

Is 200MB of data enough for an iPhone 4S?

I won't use much internet. I'll use my phone for: calling my mum (like, once a month) after school, texting, apps (eg: Instagram, Tumblr, Skype and other games like doodle jump etc.) and listening to music. Is this enough space or should i get one of the following options: 500MB, 1GB or 2GB. I'm buying this myself! So I don't have too much money!

What happens if i'm hospitalized for anorexia?

So here's a brief explanation: i'm 16 i weigh 100lbs and i'm 5'4.5. Anyways my psychiatrist told me that if i ever go under 110 lbs he will have to tell my parents and possibly hospitalize me. I've been an outpatient for almost a year and i didn't get better but i'm actually willing but my psychologist keeps focusing on my issues with my rather than my body image issues because the last i went to her office i was at a healthy weight so she thought i'm fine. Anyways i haven't gone to my psychiatrist since April but my parents want to schedule a new appointment next week because they want to talk to him if i should stop my anti depressant or no. However i'm very nervous and scared but i'm willing to take recovery but ihave a few questions: if i'm hospitaliZed what kind of therapy ill be taking?(group therapy, individual, music.) will i be allowed visitors? Will be allowed to have my iphone, ipod, laptop? What about school? I'm starting school in 10 days. If i request that i don't want any visitors will they do that? Keep in mind i'm going to be in a hospital not a rehab center. And please share your experience and tell me more about it.
