Updating iPhone 4 jailbreak?

My husband and I both have jailbroken iPhone 4 on nTelos. (Please, do not go through the legalities of jailbreaking as it is still legal and these were purchased way before Jan 26, 2013.) We had a store do them for us. What I want to know is how to update to the newest jailbreak and still be able to have our service without it reverting back to Verizon or Sprint. Anybody done this and had it work successfully?

Other iphone apps to download youtube videos?

I have McTubePro on my iphone. It downloads the youtube videos nicely BUT when I try to shuffle the music videos it does a horrible job. It repeats the same videos and doesn't shuffle them equally… Any other apps out there that actually work good? It would also be nice if I could download a whole playlist at once.

New mac laptop! ITunes sync issues?

I just got a new MacBook Air today! It's my first apple computer, I'm switching over from a Dell and I'm having some iTunes issues. I have a lot of music that I bought off of the iTunes store but there are quite a few songs that are in my iTunes library that were not bought through iTunes but are just in the library. Since I'm having to switch all my stuff over, I'm having some issues. Most all the music that I had bought is already in the new iTunes library on the MacBook because of icloud I think. When I hooked my iphone up to the mac, it asked if I wanted to sync my phone library (with all my songs on it) with the new itunes library that doesn't have all my songs on it, which would mean I would have to erase All my songs off my phone and replace it with the few I have on my new computer. What I'm basically asking here is, how do I get all the songs from my Iphone onto my new computer without erasing them all? Sorry if this is confusing!

Is it easy to replace the iphone battery?

I have an iphone 3gs and I need to replace the battery as its completely had it.
I got a quote from a phone dealer who said to replace the battery is between $70-$150 depending on where I go.
I have seen sellers on ebay selling the iphone battery and tools for about $30.
It is easy to replace yourself or should I probably get it done somewhere?
