Why PowerBuilderand Appeon?AT&T has invested millions of dollars into this large scale application. It has been keptcurrent with versions, infrastructure and needed a mobile facelift.It would have been too costly to rewrite our client/server app and we needed a ipad, iphonemobile enabled.With support from Appeon and their partners, we made some minor changes across the appand delivered a mobile enabled version within a few months.Since this time, another large scale app called the Integrated Billing System has decided tomove forward with the same approach for their PB app.elevate.appeon.compage5
