Does ios7 work well on iphone 4, 4s?

Ios7 was released for developers and I heard that ithe beta version is really bad on iphone 4 and crashes all the time?

I was wondering is it really bad on iphone 4? What about 4s does it work fine there?

No. Don't update to ios 7.It's crappy

Yeah it'll work on iPhone 4, iPhone 4S, iPod touch 5th generation, iPhone 5, iPad 3, iPad 4, iPad mini,

What part of beta dont you understand?

Will ios 7 work on ipod 4th generation

I cant get neflix to load on my iphone 4 on ios7

Do not put it on iPhone really bogs down.way too much really shortens worth it.wait for next few updates.
