How to delete old iPhone back ups and library data?

I'm trying to free up data on my iPhone/laptop and I know restoring your phone and reuploading things frees up space (at least it has for me) but I don't have a lot of laptop space. I've tried doing it before but it says I don't have enough space and the current back up that I'd attempt takes up space. I was wondering how can I delete old back ups for my phone/library.

IPhone Screen shows no image whatsoever?

All of the sudden my iPhone 4S broke down. I can hear texts coming in and Siri is able to beep in (but do nothing) yet my phone shows no image or light of any sort. This happened out of nowhere (phone wasn't dropped or broken) and sadly in the middle of a very important texting conversation. Any help solving this issue would be appreciated. I've also tried resetting it and although it is evident that a reset is possible (deactivates any noise) it starts back up with no white apple sign and clearly isn't fixed

I have been locked out of my Hotmail email account

I went to login to my email today on the computer as normal, same password etc and it kept saying it was wrong - I tried too many times and now I'm locked out!

However I'm still logged in to my emails on my Iphone… Is there anyone I can email about this problem - because the phone code is linked to another phone which I don't have anymore, and the other email for reset I no longer have access to either

Why won't my iPhone 4s show incoming calls?

Having a little problem with my phone.
But first, a little detail. I have a Sprint iPhone 4s with iOS 7 (Beta 3). Everything else works fine on the phone.
I receive all text messages, notifications and such perfectly. But when it comes to calls, I sometimes get them, sometimes don't. This is especially a problem for my mother. She is threatening to take away my phone if I do not start answering her phone calls. The problem is… I don't even GET her phone calls. She thinks it has something to do with iOS 7, but I have no idea.

Any ideas to as why this is happening?

I'm having sound issues on my IPhone 4S?

I have had my iPhone for a couple years now and it's been in great shape. However, lately I have noticed my sound to play music decides when sound should be played. It doesn't allow me to turn up or down the sound at all. It simply does not play sound. Then after sometime it plays sound like before. When it decides not to play sound it can play through headphones. I was listening to a song and it shut off. I grabbed headphones and plugged those in and the music continued playing. The I noticed where the sound bar is located was words when you unplugged the headphones. Those words said dock connector. What's wrong with my sound an how can I fix the problem?
