If i buy an iphone now, does it have the update?

Okay so i have to wait a while to get a phone and i wanted an iphone, but i don't really like the new update how everything looks… If i buy the iphone 4 or 5 in a few months will it have the update or will it be the old version?

Both of these phones (as long as it's not the iPhone5S or the iPhone5C), should have the old iOS instead of the newer one.

Yes the phone (no matter what model 4, 4s, 5 will have the most up to date software.

The iphone 4, 4s and 5 have the old ios software

The new iOS is great, you will want that once you get used to the new look
