What happens when you unjail break a iPhone?

I had my iphone 5 jail broken by my friend (he and his sister has theirs jail broken). I did it so I can get free apps. But now my weather app doesn't open up (I don't know if the jail breaking has to do with it but) and I also know that if you need service for your phone the company won't fix it because its been jail broken. My phone is with sprint. If I unjail break it will i be able to get service from the company and other stuff? My friend said he'll be able to unjail break it but it will take a while to do it. I'm wondering if my settings and and everything will go back to normal and the company won't know I jail broke it.

ITunes completely confusing?

OKay, I had an old laptop and it had tons of music on it from limewire. I downloaded some of that music to my iphone. Well that computer crashed and i got a new one. And i'm trying to get my songs from my iphone to my new computer and i don't wanna make a backup of it. I just wanna get the music on there. And every time i go to "sync music" it wants to delete everything. So are there any ways to get my music on there? And i could buy them all on iTunes but that would cost like $200… Suggestions please! And if you know any safe free music sites please list!

How much does it cost for sprint to fix an iphone 5 screen?

Ok, So i was taking a picture and I dropped my iphone 5, and at first, I did not notice a crack. But then maybe 25 minutes later i checked and my iphone had a crack. It is not very big though. It starts at the left above the home button and goes to the bottom right corner. So pretty small. I don't have insurance though! How much would this cost? I got it last november.

How Much GB should I get with a iphone?

Okay, so I want to try and save up for a iphone 5. But I don't know how much GB I should get?

I would have around 70-90 apps. I wouldn't have like 3000 songs or anything, since I could just use my mp3 players radio or my alarm clocks radio, but maybe like around 300 songs. And I wouldn't really download movies, maybe 1 or 2. I would take eh, a lot of pictures, maybe like 10ish a week regularly, and like 300 if I go on a trip ect. And I would take a lot of videos when I'm on trips ect.

So to summarize all that…

Apps: 70-90
Music: 300ish
Pics: 7, 000
Videos: 200
Movies: 1 or 2
