I had a chance to check out Radioshack's Twitter(@radioshack) and they will begin preordering Tuesday in addition to AT&T/Apple. They've also sweetened the pot and they offering a $100 credit for a 3G and a $200 credit for the 3GS towards the new iPhone 4 as long as you're upgrade elgible. Now some are going to say that they can get more on CL, eBay, etc. which is true, but some such as myself if I only have to come out of my pocket with $100 and some change for a 32GB iPhone 4 then this works for me as oppose to spending $300 and some change. They should be releasing participating stores soon as I will be at one Tuesday morning. They do require a $50 deposit when you preorder with them which I think should guarantee you one out the gate. Hope this helps some and informs others. Have a good one.
