I realize now that I wasn’t being specific in my last post…the iPhone OS 2.0 should be announced on Monday, along with a possible announcement of a new 3G iPhone. Again, speculation at best.
It may be worth it to wait a couple of days, as some programmers out there are working on a jailbreak for 2.0.
I will add that the latest rumors indicate that the online app store is supposed to open this Monday as well, which will only be compatible with iPhone OS 2.0. So those who would want to access this new app store would first need to update their OS to 2.0.
