My 3G, Black 32GB was ordered on 04.11.11 with a ship date of 05.02.11 & delivery on 05.04.11. Actual ship date has been 04.29.11, still with delivery estimated on 05.04.11. I was hoping for a moved up delivery date - it's hard waiting!
Did you order from Apple or one of the carriers?
I ordered my Black 3G 32GB from Verizon on 04/08 and just looked on the VZW site yesterday and was informed that the shipping date is tentatively 05/05, but I just looked again and all it says now is "Your order is being processed, please check back tomorrow".
This waiting and not even knowing anything really SUCKS!!!
