Well, first of all thank you all for the quick replies. This was way easier than I thought it would be, I've been used to establish an activesync connection before flashing, I didn't even know that I can execute the boot loader with a key combination.
I followed the steps above, reflashed Mighty's ROM and everything looks normal. The PDA ROM Update utility couldn't show my current firmware's version before flashing Mighty's... I thought that was strange.
In any event, thank you all again for the help! I've fixed my phone and learned something new!
On a side note: Mighty's ROM is awesome, I don't think it was at fault for my phone getting stuck at boot... I blame the texas sun, I think my flash memory got a heatstroke and forgot its contents
