    Hi everybody,

    While waiting for a possible solution in the issue I am facing with b4i-bridge in which I cannot connect as seen in the previous post to save me some time I tried to create the following class. Could someone with more knowledge in Objective C correct the code of this class I created by sewing different examples so that it works and return if the internet is connected and what type of connection there is... (I tried to compile it with hosted builder and I get an error about reachability.h as to compile it there is no need for b4i-bridge - by the way any help on the b4i-bridge issue will be highly appreciated).

    Original code can be found in:

    Code of class:

    Sub Class_Globals
    End Sub

    'Initializes the object. You can add parameters to this method if needed.
    Public Sub Initialize
    End Sub

    Public Sub GetConnectionState() As String
    Dim no As NativeObject
        no = Me
    Return no.RunMethod("getConn"Null)
    End Sub

    #IF OBJC

    - (NSString *) getConn: {

        #import "Reachability.h"
        #import <CoreTelephony/CTTelephonyNetworkInfo.h>

        Reachability *reachability = [Reachability reachabilityForInternetConnection];
        [reachability startNotifier];

        NetworkStatus status = [reachability currentReachabilityStatus];

        if(status == NotReachable)
           return @"none";
            //No internet
        else if (status == ReachableViaWiFi)
            return @"Wifi";
        else if (status == ReachableViaWWAN)

        //connection type
        CTTelephonyNetworkInfo *netinfo = [[CTTelephonyNetworkInfo alloc] init];
        _carrier = [[netinfo subscriberCellularProvider] carrierName];

        if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyGPRS]) {
            return @"2G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyEdge]) {
            return @"2G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyWCDMA]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSDPA]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSUPA]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMA1x]) {
            return @"2G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORev0]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevA]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevB]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyeHRPD]) {
            return @"3G";
        } else if ([netinfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyLTE]) {
            return @"4G";



    #End If
