apple stores had tons of them fri ,i waited in line for an hour at a att store only to have them run out of phones 4 people ahead of me.i ran to the apple store in the mall and walked in and out with one.i was already an cingular customer so it took only 5 minutes to activate it on itunes.i had a blackjack before this, that had edge and 3g,3g is definately faster but isnt available in all areas,so most of the time i was on edge anyway.edge seems faster on this phone for some reason.the phones do have a removable sim card but are locked to att,im sure someone will unlock them soon. check here for alot of info
