my iNNOCENCE Group Pre-sale code just worked for the NY show on Jul 30 an hour before the actual time (11am EST instead of 12 EST) ...
Maybe a glitch in ticketmaster but those who want pre-sale tickets, no need to wait till 12pm EST!
The presale started at 10am EST.
From U2.com: "U2.com subscribers who have not yet used their unique pre-sale access code - or new subscribers - can take part in a ticket pre-sale for these additional two shows from tomorrow, Wednesday February 4th at 10am (for eXPERIENCE subscribers) and from Thursday, February 5th at 10am (for iNNOCENCE subscribers)."
That said, I was able to buy mine via innocence presale before 10am today. Soooo... definitely a glitch.
