Sorry to hear about the misflash. I was not able to overcome the problem, and because my phone was still under warranty, I called AT&T and had my phone exchanged in lieu of "poor reception" and "lot of lost phone calls" My phone had the faulty inner antenna, so at the end they exchanged the phone. See this thread:
Your can't flash the phone back because the bootloader for the i600 is different, the RF section of the phone is also different, there is some hope because the PDA section of i600 will give you some functionality. Browsing through the forums I found this thread at xda-developers:

Is your device detected when you plug it in in bootloader mode? (boot w/keys held down, same keys you used to do the flash originally)
If bootloader was not overwritten as you say (PDA portion only, not eboot) then you can simply flash back to i600 PDA portion. But if you used the .exe upgrader without a seperate .bin, you more than likely flashed eboot + PDA, and maybe phone at same time, overwriting the eboot code with the i607 eboot code has left you with no way to access the bootloader. This situation is unrepairable without special equipment to flash the chip directly without needing access to the bootloader.
Your only software based hope is something like http://forum.xda-dev...ad.php?t=334667
, combined with a modified SPL, might allow you to load an operational bootloader and successfully flash. Unfortunately there is little interest here for samsung devices, so you are pretty much on your own with that..
I haven't tried this yet, but in a nutshell, I believe with some limitations, your PDA still works, so in order to get files into your phone you may use a microSD card. I think what you need to do is:
1) Get a working bootloader for i607 and place it into a flash card.
2) Get the JumpSPL executable from the thread above, read instructions and place it into flash card.
3) Using a file manager, move those files into \My Documents
4) Execute JumpSPL, Load the bootloader file in memory and jump to the start address
There are things you need to find like what is the start address for the bootloader code, if everything runs well, your phone will be immediately placed into bootloader mode, now running direct from memory, then using the ONENAND flasher, you may be able to flash back the eboot section of the phone, the phone RF section and the pda firmware.
