Apple has seeded out its 3rd beta of Firmware 3.1 to developers which supplants the recently expired 2nd beta.

Along with the usual bug fixes, beta 3 comes in at 307MB but brings some more improvements. Copy and paste for videos has been improved allowing the capture of bigger files as Justin of WhenWillApple explains:

“I was able to copy, paste, and email a 33 second / 14.7MB file through gmail. I got the file at the full 640×480 / 30fps. Sending the same file via the share function yeild a file size of 3.21MB at the compressed 480×320 / 30fps.”

Also, a counter for tethered data appears alongside cellular data usage in the network settings.
