Error with ios application if there is no internet connection on the devices

I have an application on the apple store, if the device is connected to the internet, the application works well, otherwise, if the device is not connected the application doesn't open, what I want is to popup a message to tell the user there is no connection, or if there is a method to launch the application with the last page opened on this device (offline browser).
Thank you per advance
You can use the Reachability library for your purpose. This library handles the Internet connection states.
To load from the last saved data, you can use Property Lists or Core Data.
You could use Apple's Reachability class to receive notifications about your network status.
#define kReachabilityChangedNotification #"kNetworkReachabilityChangedNotification"
set up a observer for the above notification and when you receive it act accordingly.

though you can get the list using the stumbler source code http://code.google.com/p/iphone-wireless/ but this is undocumented API and if you wish to submit your app to the app store then it will get rejected , but will be ok with enterprise applications..

Handling tone dial for cell phones

For example I call on the specific phone number and automaticly connect to some kind of server(?) which is able to handle all my actions while I'm connected. I want to try myself in coding this server, but I have no idea how to start =) Please give me some links to read about this or maybe some keywords to google it. Thanks a lot!
Actionscript3 will handle either web applications or desktop applications. Since you're talking about using a cellphone , I doubt you can achieve what you're looking for with AS3.
You could consider a web application whereas a user would connect to the internet via her phone and interact with your application but as far as calling a number and get some form of server response, you may have to look at using another language than AS3.
