Non-Apple-sponsored app stores and app-installers have hinted at threats to Apple's own iPhone's iTunes App Store. One of these, called InstallerApp, (previously covered on iPhone Atlas), was recently upgraded to version 1.1.
InstallerApp has seen a few improvements since we last looked at it. It now works on the upcoming Mac OS X 10.6 Snow Leopard, has removed unsupported Installer repositories, and gives more attention to jailbreak solutions using PwnageTool and redsn0w. Additionally, it supports packages from either Cydia or Icy iPhone apps that allow you to install more apps on your iPhone or iPod Touch, and its hard-drive footprint is greatly reduced to 1.2MB on Mac OS X and 4.2MB on Windows.
The big bonus--at least for jailbroken iPhone users--is that InstallerApp features the installer package for GV Mobile, the controversial iPhone app, blocked by Apple, that gives you access to Google Voice from your iPhone. GV Mobile is just one example of the packages that are available for installation on a jailbroken iPhone--4,055 installer packages were included with InstallerApp at press time.
Note: Jailbreaking your iPhone or iPod Touch may void your warranty and violate the terms of your agreements with Apple and AT&T. We do not recommend jailbreaking your iPhone or iPod Touch.
