Reachability app iPhone OS4 SDK issues

Apple's reachability application crashes at runtime after successful compile. Given the开发者_开发技巧 extent to which these routines are implemented, has anyone discovered the correction for this?

Thanks ...

I get rid of the crash by commenting the line 175 of the Reachability.m file:

173 + (Reachability*) reachabilityForLocalWiFi;
174 {
175     //[super init];
176     struct sockaddr_in localWifiAddress;
177     bzero(&localWifiAddress, sizeof(localWifiAddress));

Since the 01/06/2010, there is a minor bug fixes.
