After a lot of analysis, discussions and preparations, today we announce that WAP/WML support has been removed from MobileFrontend. Our sites were running HTML only for a couple weeks now, so since we received no complaints, we pulled the trigger. Final deprectation might take a couple more weeks, but we're already beyond the point of no return.
I would like to thak everyone who participated in this effort!
This wasn't an easy decision, however the share of WAP has fallen tremendously and we can find better use for engineering resources we would have needed to maintain WAP support functional.
