Received in email from Apple:
As a developer actively working with iPhone OS, we would like your help in a private test of the Apple Push Notification service. For this test, we have selected AOL’s AIM Developer Preview for iPhone OS 3.0 to create a high-volume test environment for our servers.
I wonder if they are hoping to drum up interest and adoption of PNS, which has received a luke-warm reception from many developers. Putting that aside, I’m surprised to see Apple asking the developer community for help, pro bono. Considering how consistently poorly they treat third-party developers, that’s some nerve.
