Hey all, first post here. I'm thinking of getting a 8GB iPhone within a month or two. I'll get a 16GB iPhone if the $100 price drop rumour is true -- when can we expect to hear about that if it's true? Questions... *I currently have a BlackBerry Pearl(8100) from AT&T.* If I were to get an iPhone at an Apple Store, could I simply switch the SIM card from my BlackBerry to my iPhone? Would I get service, be able to text(for the regular fee, without any plan), surf the web, etc... basically all the things that others do when they purchase an iPhone + phone plan at the same time. Thanks.
