I lost my iphone calendar events

I was adding an event in my calendar on my iphone 5 and all the sudden everything was deleted. I don't know what happened, but everything is gone. I tried going to my icloud account and going to my calendar to see if the events were there, but they were deleted on there too. There was a bunch of important things in the calendar so if anyone knows how I can get it back, or what happened I would really really appreciate it.

How does jump! Work if you pay the full retail value on t mobile?

I really want to get the new iphone on t Mobile. My question is how does jump work if you pay the full retail price. Bc from what I understand you have your phone for 6 months then you can upgrade to a new phone and the balance you had on your old phone I guess gets erased. And you start over with the new phone. So basically like your renting a phone. Is this correct? But that is if you chose to do the monthly payments

I want to pay the full price. But I've read that you don't qualify for jump if you pay the full price. Is this correct?

If I didn't activate the Find my iPhone, will it still be able to track it?

Lost my iphone and I didn't know about the Find my iPhone thing. I used my mom's iphone to track the phone with this app but it says offline. Is is offline because the phone is turned off or because the Find my iPhone is not activated? Should I report this to the police? Will they be helpful because it was stolen in Philly but I live in Jersey. I just got the phone not even a month ago. Are there any other solution to find a stolen phone?

Why isn't my iTunes letting me get songs on my iPhone?

Whenever I download a song, or get new music, it shows up in my iTunes on the computer, but after syncing my phone to iTunes the music doesn't show up on the phone.
I don't know if this is important, but, I share an iTunes account with my dad and sister, I've gotten the most recent updates on iTunes, and it's an iPhone 4S.

Can you use a regular iPhone with the AT&T go phone plan?

I want to use the prepaid go phone plan of AT&T. I understand that you can use an unlocked phone with it. I want an iPhone but I don't want to pay the enormous $700 for an unlocked one. I was wondering if you can buy an AT&T iPhone that's not unlocked from their website. Would that still work?

How long would 250 mb of data last me?

I want to get an iphone 5 but the cheapest plan for it would be $70 a month but it only has 250 mb of data. I have NO idea how much that is or how long it would last me. I would really only be using it for imessage, twitter, and instagram, and very very rarely (Like once a month) facebook, snapchat, checking email and weheartit (for a couple minutes). Everything else I would use with Wi-Fi only. And when I'm at home I would be using only Wi-Fi. I would really only be using the data when i'm out of the house and sometimes at school.

I would mostly only be using it for imessage and twitter. Would 250 mb be enough for me? How long would it last? Any and All help would really be appreciated, thanks for your help! <3

Added (1). I would be on twitter for maybe an hour or 2 throughout the day but I wouldn't be uploading pictures on instagram a lot only looking and I wouldnt really be using snap chat a lot either lol.

Added (2). Oh and I would be using imessage a lot too.

Ipas 2 is stuck at recovery mode

Okay, so last night I finally (Yes, I know late) got a ios 7 update and so I went ahead and updated it, my I pad 2 was charging and once I waited 6 hours it said that it need 50% of battery to update so I tried again and it sent me to the "itunes connect" logo, like the one when you first get your ipad or iphone, so I did. When I logged onto iTunes it said it recognized the ipad in recovery mode and that i need to restore it, so I was like okay this is going to be easy. But its NOT.

I then tried to restore my ipad 2 and it said it would delete all my data and set it back to factory settings, now this what I was upset about, I did some research and it said I could back it up or go onto icloud and get all my data back after I restored it but the thing is, i can't back it up because i have no icloud. What I want to know is, Is there anyway I can get my ipad out of recovery mode without restoring it, because if I restore it I lose all of my data and I have some really important things in there that I can't lose! Or if there's any other way I can save my data from my ipad THEN restore it?

P.S - My ipad 2 was at 4% when I tried again (I know. I'm stupid) but, since last time the update took 6 hours I figured if I kept it charging by the time the update was finished it would have more than 50%! So now if I try to rest my ipad 2 by pushing the home buttion and lock button at the same time it dies, and if i charge it while its on the i tunes logo it DOESN'T CHARGE.

Should I just go to the apple store?
