I don't want to upgrade my iphone to IOS 7?

I'm very nervous about the new upgrade for the IOS 7. Do I have to update my phone to the new software. Is there another way to get rid of that number that is on the side of the setting app. Beside using the Cydia. I really don't want to upgrade my phone. Is there another way to get rid of that number that is on the side of the setting app instead on using Cydia. I really don't want to upgrade it. I hate changes especially to my technology. Can someone find me other way to get Cydia on my phone because I went on so many different websites and they said the websites do not work anymore because of apple and I will have to wait until the IOS 7 comes out and I really don't want to upgrade it.

I'm pretty sure if you want to jailbreak it just type "Iphone 5/4s/4 jailbreak (#)". If you don't want to update your phone, don't update it.
