Hi Crisb, thanks for your interest and care in helping us to improve our guides. I’ll see if I can address your two points:
1. In the [http://www.ifixit.com/Guide/Installing+iPod+Touch+4th+Generation+Front+Panel+Replacement/3639/|iPod Touch 4th Gen Front Panel] guide, we recommend the use of a heat gun or hair dryer in a circular pattern for even heat dissipation. Like you say, we refer to using a “low” setting. Just like most people don’t usually use a thermometer in their microwave dinners, we don’t expect our readers to heat up their iPods to a specific temperature, so we don’t give one. In general, be cautious and use the lowest setting available so you don’t overheat components.
2. You’re correct that in [http://www.ifixit.com/Guide/Installing+iPad+3+4G+Front+Panel+Assembly/8654/1#s38868|step 24] of our iPad front panel replacement guide we’re showing a Wi-Fi version of the iPad. The procedure is identical for all varieties of iPad 2 and 3. The reason we mention the Wi-Fi antenna (in step 11) but make no mention of the cellular/GPS antennas in the opening procedure is not neglect, but because the cellular/GPS antennas are physically very different, and much more ruggedly secured to the rear case. They are not at risk with our opening procedure.
Your last two suggestions are very interesting! I’ll definitely pass them on to our tool department, and it’s great that you’re sharing them with the community. If I may offer a word of caution, using a flatiron could be very dangerous for your device if you aren’t careful. The benefit of the iOpener is that once it’s applied to the iPad, it doesn’t get any hotter, and transfers only a safe amount of heat to the iPad’s adhesive, minimizing the risk to your LCD and logic board.
