You can now enjoy your TI graphing calculator right from your iOS6 Device! jsTIfied, Cemetech's online TI-83 Plus and TI-84 Plus emulator, is now a fully-functional emulator for Apple iPad, iPhone, and iPod Touch devices. The key breakthrough to make this a reality is the ability to encode a ROM in JPEG image data. You can use jsTIfied on a computer to export your ROM as JPEG file, which you can then send to your iOS device over iCloud, email, DropBox or iTunes. Once completed, you can navigate over to jsTIfied and upload the image as if it were a normal ROM. The steps required to download the image are on the jsTIfied page under the "ROM" tab. Remember that sharing of ROMs is illegal, even in this JPEG state.
Some drawbacks to using jsTIfied on your mobile device are speed and the lack of repeated button pressing. For speed, if your ROM fails to load it's best advised to close all of the apps that are running in the background. If you're still struggling for speed restart your device. The iPhone/iPod will run significantly slower than the iPad and in turn, the iPad significantly slower than the computer. When using the mouse in Doors CS, iOS will select the HTML box that contains the on-screen calculator and ask you if you'd like to copy it rather than continue that key press which will make navigating slightly more difficult as well as games that require you press and hold buttons, perhaps even pressing them rapidly. As such, jsTIfied on your mobile device is recommended for actual class related calculations!
