So my point is simple - jailbreak is no longer needed in its "traditional" form for most people. This is why we have developed a tool that does something else... and it's absolutely amazing. Here's what it does: it puts some tools (including our own Installer) onto the user partition of the phone without opening the system partition up! You get Installer, a whole world of third-party tools that didn't got into the AppStore for some reason, such as Kate, Qik, Snapture, and dozens of others, all that without compromising your security!
The tool is named Pusher (mostly because it pushes some things onto the iPhone, and because we found the allusion funny). It works for both 2G and 3G phones running 2.0.2, 2.1 and 2.2 firmwares. Simply download it, launch and follow the instructions on-screen - the whole process takes about 3 minutes.
To make your life even sweeter, we went ahead and added a few things for free that we thought might be useful - an alternative system font, an ability to set your SpringBoard background, two alternative Cyrillic keyboards, and a few other extras that might become useful. The Mac OS X version is available for download immediately, with a Microsoft Windows one following shortly after.
