Will ios 7 delete everything?

So I'm planning on updating my iphone 5 to ios 7 and I don't want it to delete things. I have so many pictures I need and apps that have content on them that I need and if I delete it it'll be gone forever. Can I get everything to stay without backing it up because I don't have a laptop to put everything on

IPhone not connecting to my Wi-Fi?

It's an iPhone 4, and its jailbroken. The jailbraking isn't the issue because i have jailbroken the device a very long time ago, and since then my Wi-Fi was no problem.

I try connecting to the network, and it just says its connected, but the 'tick' near the Wi-Fi name is not present as it should be.

I have tried resetting my network connections on the phone and that did not work. My Wi-Fi is not the problem since i'm currently using it on my laptop and it is running as normal.

Any fix to this would be much appreciated.
