Do I need 2.5GB for my iOS 6 update on my iPhone 4?

I have a 16GB iPhone 4 with 0.65GB left on my phone. It wouldn't let me do the update through my phone because I have very little space so I connected it to my computer, opened iTunes and chose to 'Download and Install' the update. It has started to download but I haven't got to the installation part yet. At this point will I have to free up 2.5GB of space on my iPhone through deleting videos, apps etc? If i do have to free up this space, after the installation will the overall space taken up actually reduce to about 450MB (as i have heard from others). Any help would be deeply appreciated, thanks!

Fill the screen crack on iphone?

I have a iPhone 4, dropped it a couple of times (i know i know not a good idea) its missing some of the glass now (less than a small fingernail) in the corner (doesn't affect/ go near the screen itself) however i keep catching it and its sharp, anything i could fill it with? I don't care if its messy, so long as it can fill the hole and can stand the heat that the iPhone sometimes gets then Yei! Please please any suggestions? Its dropped again today and another piece fell out so it catches even more than before.

Can the Nokia Lumia 900 get android apps or iphone apps?

I was wondering if there was any possible way to get the apps from the android network or iPhone marketplace and put them onto my phone. I recently got the Lumia 900, I love the phone and everything about it is awesome, but I can't find a lot of the apps that I used to play on my old phone which was an iPhone 4. Does anyone know of a way to either download or buy apps from other market places and put them on the phone? If so please let me know. Any information is very much appreciated.

Why does my iPhone 5 stop sending messages?

It worked for a few days and then last night it stopped sending and receiving texts. But I could still make calls. Then this morning it started working again. But now it is doing it again and it won't send texts. The iMessages won't go through either. I'm horrible with technology so I really don't know what to do. I tried turning it off but it didn't work. And If I do a network or hard reset, then will I lose everything on it?

Added (1). It is a Sprint iPhone if it matters.
