I just got off the phone with a CSR at AT&T. I was able to successfully order a cyan 920 /w a cyan wireless plate for free (she said she couldn't find the black in their database so she just picked cyan to match
), at the total price of $139 (tax included). It was a bit of a fiasco for me and spoke to 2 prior reps before encountering this helpful one. I attempted to pre-order last night but the price was showing up as $199.99 and wasn't crediting me for the wireless plate.
I guess it's hit & miss with the online orders going through. One friend of mine had no issues ordering his cyan 920 online; another couldn't check out. FWIW, calling in and hoping for a 'good' csr is your best bet.
Good luck to everyone!
