Apple has released firmware 3.1 beta 3 to developers. The firmware has been found to have a few cool new features (see list below).
Note: If you are a developer, you will need to update to 3.1 beta 3 before July 29th because 3.1 beta 2 expires at midnight on the 28th.
• Copy and paste videos – You can now copy and paste videos in your e-mails. There is a 15 MB limit for copying/pasting videos or images. This limit is most likely there to save bandwidth usage (see demo video below).
• Tethering counter – If you go to Settings -> Genral -> Usage on your iPhone, you’ll notice Tethering data which shows how much tethering you’ve used. Note: Tethering is not available to AT&T users yet.
• Springboard icons – When you hold down the Springboard icons they no longer vibrate.
• Baseband updated – The baseband has been updated to 05.11.04.
