Q: ios 7 for iphone 4

What do you mean?

Ios 7 is compatible with iphone 4 now.

Yes it's compatible but it's clearly not made for.

We have no idea what Apple will do.

If you wish to let Apple know about this problem post at http://www.apple.com/feedback/iphone.html

There are a lot of feedbacks with iOS7 causing iPhone4 and 4s to be slower. Already in the beta testing phase this was pubilcised.

There may be or not be an iOS7 update in the near future but for now there is only the possibilty to set the settings optimally for solving this:

Hola, cuando sale el iPhone 7 unlocked ?

Posting at the bottom of a thread that has been dead for three years on a totally different subject is certainly not the best way to get your question noticed.

In addition, speculation about unannounced products is a violation of the TOU and ground to have your post deleted by the Hosts.
