[Question] how to use iphone in japan...
hi, i am on a locked but jailbroken att iphone and am headed to japan in a week. i have a couple of questions.
1) I was wondering if i should simply create a pwned firmware that is unlocked and restore my phone with it so i would be able to buy a local sim to use in tokyo. Would i be able to return to the phones original state (locked) by simply restoring with a locked but jailbroken pwned firmware or is there more to it than that?
2) can anyone recommend what type of simcard to get in tokyo that will be fairly cheap and also allow me to use the internet (edge, though i dunno if they have edge in japan?)? can i get on an open wifi network pretty easily in tokyo?
3) are there any apps like metro (singapore subway map app) for the tokyo subway?
4) will i get laughed at for having such a low-tech phone compared to the agg shit thats the standard there?
and finally if you know of any cool tech shops or crazy arcades to check out while im there you can let me know as well. Im super excited to go, thanks to anyone who helps.
