Games developers and publishers have reacted with huge enthusiasm to the iPhone 3.0 software upgrade announced last night by Apple.

We've been canvassing games firms since the announcement, and it has to be said that 98 per cent of their comments are positive: they're champing at the bit to get cracking with the 1,000 new APIs outlined at yesterday's event.

Here's a snapshot of some of the views we've elicited, with links to the full articles:

Tim Harrison (ex EA Mobile)
"While the wider mobile industry struggles to adopt and adapt to the new realities of Mobile Web 2.0, on a Tuesday morning in March, Apple has gone and created a 3.0rd." (read more)

Kyu Lee (Gamevil USA)
"Updates and overall play-time is going to be a much more important factor in the future for iPhone games, since a lot of these publishers will see the ARPU increasing across a handful of quality games, instead os seeing revenues coming from a large quantity of mediocre games." (read more)

Nigel Little (Distinctive Developments)
"We're really excited about the push notifications and how we can use those to alert players to what other players have been doing within our social games... we could do team based games where you and your friends play as a team and you can let your other team members know that you need their help ASAP to succeed."

Brett Seyler (GarageGames)
"I think there's huge potential to mash up music and games in a really innovative way, particularly when the app can access a user's library of music and video." (read more)
