No connectivity with iPhone 4s

David - I am trying hard to understand your question. Can you start again? Try to give details as to what you are trying to do, and what you are seeing. 

Also, do you have access to a wifi connection?

The app on my phone says "offline mode". How do I get it back on line.

David- At first glance, my answer would be that your iPhone is in "airplane mode." Let me preface my comments by telling you that I do not have an iPhone, 4s or otherwise. I do have an older iPod touch & a 1 Gen iPad 3G. I am telling you that because some of my suggestions may not apply (but I think that they do).

1. Do you know how to turn Airplane Mode on & off in the iPhone settings? Have you tried that? 
2. Have you tried a hard shut down of the phone? Press and hold both buttons at the same time for 3 seconds.
3. As I asked before, do you know if you have a good wifi signal? If not, can you find one? (I am asking about this just to troubleshoot. I know that you have 3G).
4. Do you know if you are signed in to your account? You can check by clicking "more" (bottom right button); then settings. Your email address should be listed.
5. Had you previously downloaded any resources?
6. Have you tried deleting the app and reinstalling?

Finally, if none of these things work, can you take a screen shot? [Hold down the center button, then the power button turns into a shutter release. You picture will be in the "Photos" app. You can email it to yourself there.]
