Migrating is fairly straightforward, it can import your lemmy settings to get you up and running quickly, and the systems interoperate seamlessly, which is fantastic to see.
Yes, the IMEI uniquly identifies the phone itself, so if the GSM radio is on, the network can monitor it's approximate location.
There's a couple of caveats: IMEI cloning is possible, but unlikely, and he accuracy of the triangulation will depend on a lot of factors including how far apart the towers are and what sort of obstructions there are between you and the towers. My understanding is that it is done by comparing your signal strength at each of the towers as a proxy for distance. If there's a large obstruction that reduces your signal to a tower it could throw those measurements off. They'll know you're in the area, but not exactly where.
It looks like you're going to have to reconnect a couple of traces, but if you've got some magnet wire and a fine tipped iron you should be good to go. You probably don't need that bit on the left, it doesn't look important.
The thing is, humans are astonishingly good at conserving energy when running. We can literally run prey to death by just keeping on going when most animals run out of energy.
Do we still get the sparkly, spinny transformation sequences, or is it more of a flash, and instead of the worryingly young protagonist, Mo'Gar Skullcrush stands in front of the wizard Balath, who's been causing problems, reaches forward and squashes him flat with one hand.
That has unironicaly made me nostalgic for the days when the web was a place of experimentation, joy and just a bit of crazy.
