I have had none of the problems listed here. On 2.0.0, 2.0.1, or 2.0.2 and I don't think I'll have any with 2.1.0. If the iPhone software/design was as bad as it appears on this forum who would be buying the phone?
I think things get really overblown on here (MR). As mentioned before 2.0.2 would help with the connectivity but with people refusing to update what can Apple do? Force the update when you sync?
As for the original question, I think Apple will focus on the iPod on the 9th. You might get an update, but no one here knows wether that will be 2.0.3 or 2.1.0.
Yes, you have to remember, not everyone owning a 3G phone is having problems. I have two white 3G phones and have really experienced very few problems. I have no lag, no crashes, apps always open and no dropped calls. MY 3G works in 95% of my area, the few blocks were it doesn't is clearly marked on AT&Ts coverage map.
