Can't join hidden Wi-Fi network with iOS7

Question

I just upgraded to iOS7.  It cannot join my non-SSID broadcasting wi-fi network; if I enable SSID broadcasting on my network, it joins fine; when I turn broadcasting back off, it no longer works.
The connection to this hidden network worked fine prior to iOS7.

I have a similar problem after upgrading my iPhone 4S to IOS 7.  Thought I'd mention it here for anyone else, like me who stumbled on this post.
For additional security, the SSID for my home wi-fi network is hidden.
With IOS 6 (after entering the network details manually on the first set up) the phone would remember and stay connected to the home network or connect automatically once in came within range. 
With IOS7 however, the phone seems to "lose" the network each time the autolock or passcode lock comes on or I move out of range and reverts to a GPRS connection.  I then have to go back into settings > wi-fi and wait for the phone to find the network again.  I don't need to re-enter the network details - but when I first access the wi-fi settings screen, the network SSID is not displayed then, after about 5 seconds, it displays it and the phone automatically joins the network.
I've tried "forgetting" the home network, reseting my network settings on the iphone, turning the router on and back off again and turning the phone off and back on again. This has had no effect, though.
If I change the settings on my router to allow broadcast of the SSID then the phone stays connected to my home network when the autolock kicks in but I'd rather not change the settings and compromise the security of my network.
