I contacted one of the head Techs at Dish today and she told me that the software version is not 140 but 150. Once again it is only a maintenance upgrade, which means no new features. Since I had one of the very upper level techs, I thought it was a good time to inquire about a search and caller ID option for the 501. The caller ID won't be happening on the 501. With out a real keyboard, the search feature would require a on screen keyboard taking up too much of our precious hard drive space. She indicated that the engineers were trying to get around that issue but we shouldn't expect it anytime soon. The next major upgrade should be coming in July giving us interactive customer service plus local movie information and other services. Plus it will have some sort of game feature added.
