On March 15th, vBulletin will be releasing its vBulletin Mobile Suite that I can purchase to build a PB-branded app for the iPhone and Droid. It will set me back $199 for the first year and $99/year thereafter. If you're a user of the Droid or iPhone please respond so I can get a sense of raw numbers. The app would be free but I would like to see if users of this app would be willing to throw in a few dollars per year in donations so I don't have to pay so much out of pocket.
