I have a Treo 650, provider is cingular. Palm OS is 5.4.7. Just purchased and installed Utility Bundle from RoGame (SilkScreen, Destaller Pro and SprayPaint). After installation and reset, phone was frozen, dead in the water. After a frustating 30 minutes of hard resets to get to home page and delete menu, I was finally able to delete this trash from my phone. The treo is back in business. Don't software manufacturers even test their products, before making them available to the public? Anyway, I suggest you stay away from this bundle. It's a shame, because these utilities could be a tremendous asset to the Treo 650 owner, if they worked.
