The mobile industry is as tough and competitive as any IT sector, but there were signs on Tuesday that co-operation could be the new way forward.
Fourteen operators have promised to do their bit to help instant messaging develop on mobiles. Users won't have to pay to receive an IM, but they will still get charged for sending them. So, not charity, but it's a start.
Microsoft enjoyed another big day. It has teamed up with BT, HTC and The Technology Company to create a smartphone that can handle mobile TV over a DAB network.
Intel has also landed an alliance with the GSM Association to help make laptops combatable with super 3G networks. And Microsoft's Steve Ballmer and Sir Richard Branson of Virgin took part in a remarkably friendly clinch in Ballmer's keynote.
On the technical side, Broadcom says it can make mobile calls crisper and more reliable, and Qualcomm thinks 3G phone prices are going to drop this year.
