When can I update my Iphone 4 to iOS 7?

I saw someone post about how they just downloaded the software update iOS 7 to their iphone. I went into my settings to try to start the update and it said there were no new updates. So my question is when can I put iOS 7 onto my iphone 4?

IOS 7 is not out yet. Apple will release it this fall.

This fall. Only apple developers get the beta version now, but they pay the price $$$$

If you really want to get iOS 7, buy a UDID on eBay but I mostly experience a lot if bugs so if you want to try buy one on eBay. Search "iOS 7 UDID" and you should be able to get it valid.

The free way to do this is to download the ios 7 ipsw for your iphone from a website ( there are many out there) and basically connect your iphone to itunes and press shift + update on pc ( option + update) on mac. Then select your ios 7 ipsw for the iphone 4 and then just wait till it finishes. Just make sure that your phone is acticated on ios 6 before you update or it will ask you for a registered UDID. And just letting you know, ios 7 on iphone 4 is not very good. It is slow and crashes alot. But you can try it and it and if you don't like just restore to ios 6.

I have iOS 7 beta on iPhone 4 and running without crashes. However, I agree with Omar that iOS 7 is slow and various graphics effects are unfinished. I hope, Apple will finish these deficiencies to final release.
