I'm using a 1st generation iTouch with the latest version of Tiger. It works fine but some wifi apps don't work at all. Remote is unusable because the connection is sporadic. Files, a file transfer app does not work at all. It can't talk to my Mac. Is this a systemic thing? Is the 2nd generation iTouch or iPhone better? I applied all the latest updates and it's not jailbroken. Using OS 10.4.11.
