What is the best way to keep from drifting?

So my best friend of 4 years has been drifting from me lately. We barely talked over the summer, and so I sent her texts and emails around October asking her why she has been ignoring me. She just told me that her parents got mad, her electronics were taken away, and she can't text me until December. Also, she said that because of what happened in the end of the year last year between us, she was "ashamed" to talk to me. I believed her, but at the same time, I was suspicious. The email she said was sent from her laptop and her mom let her use it to check her email and that she was in the bathroom typing it (which her mom should be smart enough to figure out) and I knew that she was literately addicted to her phone. Well, I used my mom'sinstagram to check hers, and sure enough, she was posting a bunch of photos and selfies using her own iphone. To make matters worse, I found an external link for some lame questions site, and she was freely cursing and flirting with a bunch of guys (who are relatively disrespectful and rude) which she never did in front of me. Anyway, I confronted her about it through email (since we go to different schools and we don't see each other anymore) and she just told me excuses about them. After a series of replies, she told me that she knew she wasn't herself anymore and that she went through a lot over the summer which she would explain to me later and that she will change. I accepted that, and we started texting again, but she started to ignore me about 3 days ago. Oh and recently, she was given the privelege to use her phone again as she told me (but I think she was allowed before that and just didn't tell me). I feel like I'm the only one who cares any more and I'm the only one who's trying to keep us from falling apart. She used to tell me that I'm her best friend and that we will stay together forever, but she started to hang out with a bunch of guys and some girls (which I saw on instagram) and she never asked me to do that before and she even said that her parents didn't allow her to. I don't know if another confrontation is worth it. What should I do to keep us from falling apart?

My iPhone uses way too much data?

I just switched from a Galaxy S2 on Sprint to an iPhone 5S on Verizon. I have always used my phone a lot, and on my Galaxy I used less than 150MB per month. On my iPhone I've used 414MB in the four days I've had it. I haven't used it much differently than my Galaxy. I'm on Wi-Fi most of the time as it is. I can understand a *little* more usage but this is kind of ridiculous, at this rate I'll use 4GB in a month.

I'm seeing a lot of people are having similar issues. Is there a way to fix this? I don't mean a workaround like shutting off Cellular Data, I mean is there a way to make it use data properly instead of it skyrocketing every day?

How many software updates does an apple device go through?

Apple usually does not give ios updated to older devices such as ipad 1, iphone 3gs, ipod touch 4g and older so i want to know that how many updates does a device go through like the ipad experienced ios 3, 4 and 5 if i'm not wrong. So is it true all the devices only go through 3 updates?

My iPhone 4 turns off all the time whatever battery percentage?

My iPhone 4 turns off every day, I took it to the apple shop and they said they screwed the battery back in properly as they said part of it was bent, but they didn't do anything else this was quite a while ago now it is constantly turning off and I have to press it in at the back for it to come back on, and when I release my finger it turns off.
Any suggestions as to what i could do?

Can I download illegal music on an iPhone 5C?

I have thousands of songs (well not really, just hundreds) on my android phone and most of them were downloaded for free *cough* illegally *cough* and I was wondering if I switch to an iPhone 5C, will I be able to transfer all of my songs on my old phone to the 5C?

And will I be able to download illegal songs on my PC and transfer it to the iPhone 5C?

Added (1). No, I don't have an iTunes account and I probably won't get one. But would I be able to download illegal music from my usual sites on my PC then transfer it to the 5C?

I want to install iOS 7.1 beta 2 on my iPhone 5?

I heard many users without a UDID are having activation issues (at the startup screen it says 'your iphone is not registered with the apple developer programme'.So I guess I need a UDID for that…
So my first question is this:
There are many websites that provide 'instant UDID registration'. Are they trustworthy?
For example- regmyudid.com
And my second question:
Once I have registered my UDID, do I have to install it using iTunes (Downloading a dmg from a non official website and then installing it using iTunes) or can I just do an OTA update?
Third question:
Are there any other prerequisites for installing a new iOS7 beta?
Any help is much appreciated.
