We have a shop in Fountain Valley (not sure if that's close to you). We do also offer a 30 day return policy, so we'll happily take the AP back if you're not supported and don't want to update your DME or if you don't want to wait. The vast majority of 2011 and early 2012 N55s are currently supported. I only had a total of 7 customers with the old rom and any other new roms we've received since release have been added in 48-72 hours.
Let me know if you have any other questions.
