as no one has answered this yet, I will expand it slightly - what accessory items / packages will be offered at launch. Perhaps cWeems who has been more than gracious with his information could help us here know before we arrive friday to know what will be there so we could know what else we might purchase with our new toys...
I believe my local O2 put out a leather case and a rubber case for the new iPhone 3G, apart from that most existing accessories would work I would imagine.
The guy in CPW said they are releasing protective cases "in a bit" because the iPhone 3G is cheaply made (well cheaper the last one) with not as strong materials, so one wud b needed.
spoke with at&t store manager earlier today - he said there will be a small selection of cases available on launch day (maybe 3 to choose from), but wouldn't tell me which ones. I'll pry it out of him tomorrow when I head down to his store and check out the shipment of 40 8GB's he received today
