As it is low nowadays, is it the right time to invest?

I want to switch from the Samsung Galaxy s4 to the iPhone 5s?

About 2 or 3 months ago i changed from the iPhone 4 to the Samsung Galaxy s4. At first I was really really happy with it, but now it's just causing me a lot of problems. I'm locked in for a 2 year contract at AT&T. About how much would it cost to change my phone? (ik i would have to finish paying off the phone) So would that mean I would need to finish paying off the samsung phone and then buy the iPhone? Or would i just need to pay for the iPhone?

Can I lose weight on 900 calories a day?

First off, I don't want anyones *** about i'm starving myself because i'm only eating until i'm full! If i'm full, then i'm clearly not starving myself.

I eat raw vegitables and fruits all throughout the day. Also eat a can of tuna for protien.oh, and some yogurt too.
I recently added the app myfitnesspal to my iphone to count my calories (i'm 90 lbs overweight, just recently switched from pizza and cookies n junk to vegitables and fruits two days ago)
and it shows that i'm eating between 800-900 calories a day in the HEALTHY things i'm eating.

I've been told this will throw my body into starvation mode because of lack of nutrients, but i'm getting all the nutrients needed.So, will i be able to lose weight? If so, a rough estimate of how much?

Added (1). No, i'm not eating any junk food. I'm strictly raw fruit and vegitable diet right now.

My IPhone won't connect to my Wi-Fi?

So this has only just happened, i'll click on the Wi-Fi name and it will just load and i'll wait but it never connects. The Wi-Fi has been fine on my laptop, so i don't think the Wi-Fi is the problem. I have tried to reset network settings, and re enter the password, etc but it still won't work!

Why does my iPhone keep deleting my notes? - 1

Some of the notes I had created where important and they keep deleting themselves! Is they anyway I can get them back? I have an iCloud, so I assumed they would be there, but they aren't.
