Can I get my iphone back from a thief?

I regret that I never locked it. However, I can still see new data (such as contacts) from the stolen iphone on my icloud account. It says I can change the lock on the account through icloud. Is that really possible to do? I changed the lock combination through icloud but it says will only be put into effect when the phone goes online. The phone seems to always be offline. The phone also needs to be online to track it. Is it impossible and too late to track my iphone this way?

Can't mobile disapprove a contract for f1 student?

I'm studying in USA on f1 visa and I lost my phone day before at a club. I wanted to get an iPhone As soon as possible and t mobile seemed the best option. They took copies of my passport and visa and said r takes 24 hours to get approved. I went back to the store they said they haven't received a reply yet. Because there's alot of new students applying and there could be an overload. I'm worried. Is it possible that they could disapprove? What is the authorisation based on? I have no ssn or account but they said I not need it. If you're a representative from t mobile or know anything about his procedure please answer.

My IPhone has a cracked screen. How do I make it last for seven more months?

We all get angry. So I was telling my parents to pick me up at Navy Pier, I was at the corner waiting for them and they think I'm inside the building, and we were yelling back and forth over our misunderstanding. I was so angry, I lost control, in anger swung my lower arm from up to down, but I did it so fast my Iphone slipped our of my grasp and smashed into the concrete sidewalk.

I had it for 16 months and now its smashed.

The screen still works, but it's all cracked and I don't want my parents to know. It's ok, because I'm a boy who learns to go with what he has. I can still use it, I can make this work for me, it's not over yet.

One corner of the phone was like burn black, but after I took it out of my pocket for a while, the black section reseeded back to clear.

So what is some advice, should I make a protective case for this Iphone rather than carrying it in my pocket, because I can do that. Afterall, I'm a boy who finds ways to work with what I have.
