I tried the code on android 2.2 emulator and it was working fine. Following is the working code:

private ArrayList<String> getInstalledApps(Context context) {
        ArrayList<String> results = new ArrayList<String>();
        PackageManager packageManager = context.getPackageManager();
        List<PackageInfo> applist = packageManager.getInstalledPackages(0);
        Iterator<PackageInfo> it = applist.iterator();
        while (it.hasNext()) {
            PackageInfo pk = (PackageInfo) it.next();
            if ((pk.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
                Log.v("system app using internet = ", ""+pk.applicationInfo.loadLabel(packageManager));
                continue;
            }
            if (PackageManager.PERMISSION_GRANTED == packageManager
                    .checkPermission(Manifest.permission.INTERNET,
                            pk.packageName))
                results.add("" + pk.applicationInfo.loadLabel(packageManager));
        }

        Log.v("app using internet = ", results.toString());

        return results;
    }

i had the same scenario, i solved it using the following check

PackageInfo p = packs.get(i);
ApplicationInfo a = p.applicationInfo;
if (PackageManager.PERMISSION_GRANTED != pm.checkPermission(Manifest.permission.INTERNET, p.packageName)) {
continue;
}

the packs variable is a array of class that holds information about the application installed and it consists of the objects with info of all the applications currently installed in system
