Substituting 
"/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager" with
"/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfiguration"  
works.

However per  http://blog.guvenergokce.com/iphone-wireless-scanner-ios5/170/ we 
need a jailbroken device.

However during our tests we found that issuing the stop command from the XCODE 
debugger seems to get the scan results even on non-jailbroken devices. Is there 
a way to send a SIGINT inside the code and add a handler to catch the signal to 
mimic the GDB stop. This could work around needing root permissions.

I don't know anything about this stuff but I thought of something that I'm now 
wondering about.  Like many of you I need to run my app on a non-jailbroken 
iPhone. But....  What if I had a jailbroken iPhone. Is it possible to copy the 
WiFiManager or IPConfiguration dylib off the iPhone and include it as a 
resource in my Xcode project.  Then when running on a non-jailbroken iPhone, 
use the version from my app bundle.  I don't know if this is even possible and 
if so does it get around the permissions problem?

Seems currently all the applications(include those in APP store) are not 
available for iOS5. Anyhow, the hint is Airport Utility is able to do the 
scan...
Hope we can find new solution soon for not Jail breaked iPhones.

Airport Utility, uses the string in the entitlements.plist, but it's
impossible to put the app on the device with that string.

Today I found the debug that Apple uses the 
"/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager"

At comment 57: My friend this does not work with iOS 5. it crashes me when I 
use this path.
So is not the solution. I don't know if solution will exist (for non jailbreak 
iOS devices).

Anyone have updates regarding this? Are there any hope for non-jailbreaking 
users?

hi everyone, i tested 
/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfiguration, i 
can get rssi from  Apple80211GetInfoCopy and it need not jailbreak your ios, 
but i doesn't test other APIs.

My devices are ipad2-ios5.0.1 and ipad2-ios5.1.

Could anyone please confirm yupengs findings?

If anyone could test if 
http://code.google.com/p/iphone-wireless/wiki/Apple80211Scan works with 5.0.1 
and 5.1 I would be greatful.

Apple80211Scan works with 5.0.1 and 5.1 but only on jailbreak devices. On 
non-jailbreak devices you still get the "deny system-socket" due to sandboxing.

Has anyone managed to get the Apple80211Associate method to work?
I can successfully run Apple80211Open, Apple80211Close, 
Apple80211BindToInterface, Apple80211Scan, and Apple80211GetInfoCopy on my 
jailbroken device thanks to 
http://blog.guvenergokce.com/iphone-wireless-scanner-ios5/170/ but I can't seem 
to associate to a network; any help would be much appreciated 
(going through http://code.google.com/p/iphone-wireless/issues/detail?id=20 did 
not solve my problem).
