App Rejected - Help Please

Hello,

I recently submitted what I thought was a simple application to Apple, however it was rejected for "App does not load passed the launch screen." My SDK is 2.0.1GA2 & here is my app.js. Does anyone see anything obvious because on my device, once installed, the app runs without issue.

It's a simple webview app, that has tabs that go to different external websites.

var network = Titanium.Network;
 
// NETWORK CONNECTION CHECK
if (network.online == false) {
    Ti.UI.createAlertDialog({title:'No Data Network', message:'Please connect to a data network.', buttonNames:['Close']}).show();
}
 
// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');
 
// create tab group
var tabGroup = Titanium.UI.createTabGroup({id:'tabGroup1'});
 
//
// create activity tab and root window
//
var win1 = Titanium.UI.createWindow({
    url:'activity.js',
    titleImage: 'images/titlebar.png',
    barImage: 'images/titlebarbg.png'
});
var tab1 = Titanium.UI.createTab({
    icon:'images/activity.png',
    titleid:'Activity',
    window:win1
});
 
//
// create discussions tab
//
var win2 = Titanium.UI.createWindow({
    url:'discussion.js',
    titleImage: 'images/titlebar.png',
    barImage: 'images/titlebarbg.png'
});
var tab2 = Titanium.UI.createTab({
    icon:'images/discussion.png',
    titleid:'Discussions',
    window:win2
});
 
//
// create calendar tab
//
var win3 = Titanium.UI.createWindow({
    url:'calendar.js',
    titleImage: 'images/titlebar.png',
    barImage: 'images/titlebarbg.png'
});
var tab3 = Titanium.UI.createTab({
    icon:'images/calendar.png',
    titleid:'Calendar',
    window:win3
});
 
//
// create members tab
//
var win4 = Titanium.UI.createWindow({
    url:'members.js',
    titleImage: 'images/titlebar.png',
    barImage: 'images/titlebarbg.png'
});
var tab4 = Titanium.UI.createTab({
    icon:'images/members.png',
    titleid:'Members',
    window:win4
});
 
//
// create more tab
//
var win5 = Titanium.UI.createWindow({
    url:'more.js',
    titleImage: 'images/titlebar.png',
    barImage: 'images/titlebarbg.png'
});
var tab5 = Titanium.UI.createTab({
    icon:'images/more.png',
    titleid:'More',
    window:win5
});
 
 
 
 
//
//  add tabs
//
tabGroup.addTab(tab1);
tabGroup.addTab(tab2);
tabGroup.addTab(tab3);
tabGroup.addTab(tab4);
tabGroup.addTab(tab5);
 
tabGroup.addEventListener('open',function()
{
    // set background color back to white after tab group transition
    Titanium.UI.setBackgroundColor('#fff');
});
 
tabGroup.setActiveTab(0);
// open tab group with a transition animation
tabGroup.open({
    transition: Titanium.UI.iPhone && Titanium.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT
});
 
// setTimeout(function()
// {
    // tabGroup.close({
        // transition:Titanium.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT
    // });
// },2000);

Well, for those who provided good feedback thank you. Despite it going to an external page, I am utilizing push notifications. I'm hoping I found the issue and it has been resubmitted to Apple.
