    Hey guys,

    Just got my iPhone 3G last week, and have had relatively little trouble with adjusting from my old Motorola. One thing I did notice, however, is that when plugged in and charging, my touchscreen goes mental. Unlocking the phone is a task, takes about 15 swipes to do it. All the other times, the thing only gets halfway across the bottom before it thinks my finger has gone off the touchscreen. Once unlocked, the trouble doesn't stop. When trying to change pages on the springboard, the iPhone opens an app that I wasn't even touching. Sometimes trying to open an app on the top of the screen results in Safari opening, which is one of my quicklaunch icons at the bottom. Is it normal for the touchscreen to go completely whack while charging? Once unplugged the thing works like a charm.

    Thanks in advance.

    No that's not normal. Is it doing it plugged into the wall or the computer or both? Do you have access to a different cable/charger to try? Is the phone new & under warranty or did you buy it used from someone? If it's under warranty you might want to make an appointment and bring it in to a genius to check it out.

    No, this is not normal... i think you have to take some suggestions and ideas from a iphone app developers team. There are number of networks online where you can ask your :apple: iphone app and iphone accessory relevant questions from professionals in iphone app development.

    Ok guys quick update. I brought the phone back to the resellers, and they took a look at it, but, like my Macbook, whenever I take an Apple product back to have it looked at, it fails to replicate the problem. The people said they couldn't do anything about it unless the problem presented itself. She then tried to convince me that it was a perfectly normal and common "iPhone glitch", and that i was just using it wrong. She said that if I was unsatisfied with speed, I was always free to do a paid upgrade to a 3GS.

    It only messes up when I have it plugged into the wall, not when it's in the computer. And apparently only when I'm at home or on campus, not in the Apple reseller. Where to go from here?

    Hmmm... Maybe it's the actual charging plug. Can you borrow another charger from a friend or something to try? If not I'd maybe buy a new charger and see if that fixes it. Otherwise I guess just charge it from the computer instead.:(

    It doesn't appear to be the plug either. I used mine when I took it back to the reseller. Something strange is definitely going on, but I can't get it to show anymore. I'm worried because I just laid down 500 bucks on one (it's expensive over here in China because China doesn't lock their phones to a network. They are unlocked, but we only really have one network we can use). I laid down an obscene amount of money and it definitely had a problem, but now it seems to just be hiding, ready to pop up after my warranty is up.

    Anyone else got any ideas?

    Hi, I'm in the cellphone retail\repair business. I've seen this plenty of times, but usually this is caused by your charger or usb cable (especially generic chargers). The wires aren't isolated properly and cause magnetic interference.
    Luckily it wont damage your phone.
