I've downloaded an app, freeware, from the web straight to my phone. I'd like to share the app, but am not sure how to get it from my phone to email over?
Thanks
Getting a .sis file from my phone
You don't. When the .sis/.sisx file is download and installed, the original .sis/.sisx file is discarded as the files inside are placed in various locations.
Once that has been done, it is not possible to recreate it easily on the phone.
In addition, the phone has built-in restrictions for forwarding/sending specific file types (e.g., .sis and .sisx files are on such a list, also known as CCL, Closed Content List).
