What is the difference between the iphone 5s and 5c? - 2

I'm upgrading my current iphone next week to either a 5s or 5c. I've been looking at both of them but I'm not really a tech savvy person so I don't really know the difference. Which is better overall? What are the cons? Also, which one takes better pictures? Like, sharper and such. I take a TON of pictures with my phone since I travel a lot and it's just more convenient. I have the iphone 4s right now and the picture quality is terrible. Extremely grainy and blurry, no matter what I do.so, suggestions on the two? Also, please don't suggest other phones. The only one I'm interested in is the iphone. I've tried many brands and it is what I keep coming back to. I've done the blackberry and droid and whatnot. Only iphones.

IOS 7 mobile substrate not functioning?

I jailbreaked my iphone 5 recently. Installed some tweaks that are working under ios7 (activator beta for ios7, swipeselection, and browserchooser). After a while, the tweaks stopped functioning (and they are not visible in the settings app). After some research, I realized that this malfunctioning was due to the "mobile substrate" that is not working.
What should I do? Wait for the update that evasion is working on? Or restore my iphone and rejailbreak it?

What are the differences between iPhones 4, 4S, and 5?

We had no money this December, and so we're gonna have a late Christmas in mid-January.
The question is pretty self-explanatory. Don't tell me Apple sucks or whatever, I want an iPhone and I'm wondering if the 4S/5 are worth the extra money or if I should just get 4.

Itunes won't let me restore from previous backup?

So yesterday i backed up my iPhone 5 to my computer and it said it backed up successfully etc. But when i tried to restore from the backup it does not give me the option to restore from yesterdays back up ( it only lets me back up from other back ups made in the past) but I need to back up from yesterdays one as it has the latest data.

When i first connected the phone to iTunes it listed yesterdays back up but then when i clicked on restore from back up it was no longer there.

I don't understand where it has gone? I know i backed it up so why has yesterdays back up disappeared?

Don't tell me to phone apple as they could not help me.
