Could the area the UMTS module sits on the board be made in a way for adding the module back on afterwards if say the consumer decides, after purchasing, 3G/4G without a USB dongle is what they'd rather have?Impossible, I'd say.
True. This goes for any electronic device out there I suppose, but if there's a way around it it's at least worth investigating.All this paranoia is not worth wasting gta04's time on. If you don't trust the hardware and/or software, you should just not buy/use it.
"If you wanna be invisible, then just don't be"There is no way to avoid the basic problem of trust, unless you build the device completely from scratch yourself, which is impossible (I mean not just assembly, but also designing and building every little component).
Maybe you don't trust the 3G module, so you add a kill switch to cut power to it. Assuming that you never turn it on (because the second you turn it on, who knows what it starts broadcasting to the NSA, right?), you still have to trust that the kill switch actually kills the power to the 3G module, that there is no tiny little battery embedded in the module, etc. Maybe you do some measurements with some instrument to verify things, but can you trust the measurement instrument? Etc. etc. all the way to "maybe this is all an illusion and we are living in the Matrix".
There is no way to avoid that. So don't worry too much, be reasonable and pick your fights. It makes much more sense for intelligence agencies to put backdoors in mainstream devices and key nodes of the network, than to bother with a niche device like this. Sure, the 3G module could be compromised, and the CPU, and maybe they even put some subtle backdoors in some linux drivers. To be 100% sure, you shouldn't use anything, ever.
Somehow I feel he's the only realistic person here.All this paranoia is not worth wasting gta04's time on. If you don't trust the hardware and/or software, you should just not buy/use it.
That's something to be looked at.I'm not sure whether an electronic switch to do that would be expensive, but it would probably need to carry less current, wouldn't it?How about a GPIO controlled antenna disconnect? If the module self-powers for some nefarious purpose, 'the man' would need to be standing next to you with an antenna pointed at your pocket to pick up the signal.
No reboot needed - as far as the module knows it's 'situation normal' - it simply can't find anything to talk to.
But is it necessary for it to be hardwired to the power line so that it will always and forever turn on when in use (assuming you trust Michael and Nikolaus) with no way to compromise it (short of physically cutting it)? Or do you trust the OS enough that if you tell it to turn on an LED when the module powers up?For me the LED idea would be great
I would not have a problem with it but I want people to understand what they're getting into if they do think it's a good idea. You would not be able to replace it with just any old switch, it is there for you to cut and then resolder as needed.Who is not content with 0 ohm resistor for an option they can opt in on?
#5: Short it
Pro #1: Free! Its free!
Pro #2: Most secure solution ever.
Pro #3: You can use it for about ANY function in the Pyra. Wifi, Led, BT, LCD... you name it!
Pro #4: Backwards compatible to OpenPandora
Pro #5: Proper implementation saves the battery.
Pro #6: Takes up almost no space!
Con #1: Unless the contacts are available from outside, you need to take the console apart.
Con #2: F*cked if all we got is BGAs soldered around and not a single contact.
Con #3: Shorting the power on the 3G may burn the rest... but that never happened on any device i been "shorting" unneeded functionality out from.
Con #4: Choose: Soldering iron and a wire or a chewing gum with a paperclip?
