my phone has stopped sending or receiving pics. They used to arrive in my inbox with a small version of the photo or vid with a play sign ghosted on top. now it says download, when i try to download it says download failed. any ideas??
Also what is a widget?

I had this a few weeks back and it was a network problem, so phone your network and get them to check your area for any faults, and also whilst on the phone to them get them to go through the access point names settings. It's a good idea to call them from another phone as they will need you access the settings on your SGS.
A widget is a small application that you can put on any home screen.

I had the same problem and fixed it myself......Orange were no help even though i suspect it was something they did.
