How to get ios 7 on iPhone 4S?

Please help.

My friend has it and he won't tell me how he has it which is very annoying! He says he has become a developer for apple and says we have to wait until September! :/

Iphone 4s has it own os than why do you need ios 7?

Yes it is possible. I have an iPhone 4S and I have iOS 7 I'm not a developer and to get it you'll have to lose your jailbreak… Look it up on YouTube cuz I can't explain it to you. Type "how to get iOS 7" it's the first video
