i know no one can predict the supply of the 4s, but i can't upgrade until Nov 1st which is about 2 weeks after release... i upgraded on the release day of the 4 so have no idea but does anyone remember what the 4's availablility was like about 2 weeks in? was it still super hard to find? though after thinking about it, with it being spread out amongst 3 carriers its probably hard to compare, unless each carrier gets less than what AT&T got with the 4...
