Hello all, Long time reader, first time poster. Bummer it's got to be with a support question. :/ Anyhow, my situation is like the title says, when I plug my iPhone 4 into my 150W power inverter using the standard usb cable and two-pronged adapter that comes with the phone, my multi touch functions get all twitchy. Here is the exact power inverter I am using: http://www.dealextreme.com/details.dx/sku.37247 (albeit in red) and I'm wondering if it's this that's causing the issue. Has anyone else experienced this sort of thing when charging in their car? It's most obvious when I start an inertia scroll, then put my finger down on the display to stop it from scrolling, however instead of stopping the scroll like it would normally do, it twitches out, and sometimes even acts like I made a tap selection, but often on something not even close to where my finger was resting. The issue does not persist after unplugging the device, and does not show up when charging in a wall socket. I've also tried alternate cables/two prong adapters, but no dice. Could it be that the inverter is sending it too much power and thusly causing the multi touch to freak out? When possible, I am going to see if my girlfriends iPhone 4 has the same issue, and if so, try and get a video of it in the act.
