Application crashes after installing iOS 4.2
<p>I recently installed iOS 4.2 for my iPod after then my application started to crash.</p>

<p>The scenario is: I launch my application wait until it's up and running then hit the iPod home button then launch my application again, my application starts again for seconds then crashes.</p>

<ul>
<li><p>my application is a job search engine, so in all of its navigation pages it's communicating with internet server.</p></li>
<li><p>I think the problem has to do with applicationDidEnterBackground, applicationWillEnterForeground, or applicationDidBecomeActive methods. I do not have an code in these methods and I do not know if I need to, to prevent the crash.</p></li>
<li><p>I do not understand what happens after I hit the home button and my application goes to the background:</p>

<ul>
<li>will it still be running in the background (because of the multithreading thing in iOS4.2). </li>
<li>Sometimes when I relaunch my application it goes to last page I left in before hitting the home button and sometime it starts from the home page. </li>
</ul></li>
</ul>

<p>I do not understand what's going on, I just want it every time it starts to start in the home page.</p>

<p>I was just about to submit my application to the Apple Store just before I updated to iOS4.2 and the crash starts to happen. I'd really appreciate if someone can help me with this issue that I'm not even able/or know how to debug.</p>

<p>Thanks a lot in advance.
Regards,</p>
