If you've been hacking your iPhone to get 3rd party apps with firmware 1.1.1, there's now a big reward. Installer.app has been updated, and some long-needed changes have been made. First, instead of browsing the entire collection in one huge list, you now select a category, and then browse a smaller list. Under the previous system, as the list of 3rd party apps got longer and longer, the interface for finding and installing a program became more cumbersome. With the new system, the category splitting should make finding and installing apps a lot simpler to use. Also, it should do a great job of hiding dictionaries, theme packs, etc. into their own subcategories. If you've hacked your iPhone, this should appear as an update.
