What to do about cracked laptop?

Hi… So I was on omegle (not doing anything bad) and I had my laptop at the edge of my bed. And I went to go turn on my light. And it fell on the floor. The whole screen is indented and cracked. No glass is broken, it's just indented. This happened once before, same reason. I got a new expensive screen. Should I tell my parents? Also, will omegle come up again after I get a new screen? Btw, I rarely use it, I have an iphone.

Can I still use an unlocked iphone 5c without a data plan?

Thinking about ordering the iphone 5c online from Apple, it comes with a sim card already.
I don't want a data plan.
BUT can i still use the phone to text or access apps? Will i be able to use it over Wi-Fi? And does that mean I can't make phone calls?

Added (1). Oh, and it's the UNLOCKED iphone 5c****

My notes on my iPhone delete themselves?

I had about four notes and they disappeared one day. This has happened four or five time in the past few years. It's really annoying and yes I have iCloud and i do update with it.

Will this work if I want to downgrade my iPhone?

I have an iPhone 4 with iOS 7 installed. I want to downgrade to iOS 4.2.1. I have already downloaded the iOS 4.2.1 from an Apple archives page for previous software updates.

If I connect my iPhone in iTunes on my computer and right-click "restore" and choose the 4.2.1 file, will it restore to that software version successfully?

Thanks for your help! Best answer gets 10 points!

IPhone 5 battery drains Really fast? From 30% to 16% in just 10 minutes?

This morning by the time I woke up the battery is 30%. Then, I checked my instagram for less than 10 minutes, then I got the 20% battery notification. But when I checked the battery, it was only 16%! From 30% to 16% just in 10 minutes! And then just about 3 minutes later, the battery drained into 14%. This is ridiculous. Yesterday I overcharged my phone for about 1 hour. Before that, I've overcharged maybe around 2-3 times, each overcharged for about 1 hour. I've had my iPhone since October 2013. Can someone please explain why this happened and how to prevent or solve this problem?

How to buy a iphone overseas?

I want to buy a second-hand iphone 5s online, could you please introduce me a website that offers international buying or selling? Thank you!(just buying it from another person and not shopping online)

Should I upgrade to the iPhone 5s or wait for the iPhone 6?

I currently have an iPhone 4 and I was eligible to upgrade from the beginning of April/this month. I desperately want a new phone, but September is only 5 months away, and based on the rumor mill the iPhone 6 will be a worthwhile wait for an upgrade. The only issues are that my 4 is very laggy and doesn't run iOS 7 well, and I don't particularly want a phone with a 4.7 inch screen (which the 6 is expected to have). What should I do?

This will likely be the phone I take to college on a two year contract, since I'm currently a junior in high school.
