Yeah, I miss 2G iPhone days. Dusts were there from day 0 or never. I got replacement twice to get an unit w/o dust, and it remained that way till the day I replaced it with 3G. I stopped caring about it on 3G and 3GS. Same thing for the iPad.
iPhone repare isn't priced by tiers so I don't really care how difficult to get broken display fixed. It's expensive now, it will be expensive again.
I hope I can get a good unit straight up.
