Edit: I stumbled on this nice site recently: willmyphonework.net, which allows you to check compatibility of a lot of phones in various countries. It confirmed my iPhone 6S also works in Japan.
And now for something slightly different (still tech related), I went to Japan this summer (btw, I wouldn’t recommend that: go in spring or autumn) and wanted to use a sim card in my unlocked iPhone 5S (model A1457) and wondered if it would work.
Different sub-models of iPhones have different antennas (GSM/UMTS/CDMA/LTE etc), which means an iPhone bought in one country may not necessarily work in another country due to different standards. So I tried to find information on this topic but couldn’t find confirmation on whether the A1457 model would work in Japan.
Well having been there and used it with the U-Mobile (NTT Docomo network) sim card I got for it: Yes, the A1457 does work in Japan with both LTE & 3G. I had no problems using it in Japan even in somewhat remote areas.
Now fortunately newer iPhones (6/6S) are a better kind of “world phone” than the iPhone 5S was, so I should have no trouble in the future either.
December 2015: I just wanted to note that the solution below stopped working for me after a while. However I recently purchased a Synology NAS and configuring as a Time Machine backup destination is fairly easy.
I just got a MacBook Air and had already read about how you can setup your own network based Time Machine backup on a Linux server. The problem is that there is some outdated information floating around, which caused me some headaches getting it to work with errors such as “The network backup disk does not support the required AFP features” and “backup failed with error 45” (in Console).
First: you need version 2.2.x of the “netatalk” package. Debian 6.0 (Squeeze) comes with 2.1 by default, which won’t work (with Mac OS X 10.8 “Mountain Lion” at least). Second, lots of how-to information includes instructions on creating a /etc/avahi/services/afpd.service file. With netatalk 2.2, this file is redundant: you do not need to create it.
Back to netatalk. Really old information will talk about needing to compile it from source to have it support the required authentication protocol. That is no longer relevant with the most recent version. If you are still running Debian 6.0 (still the stable version at time of writing) you can get netatalk 2.2 from Debian 7.0 (Wheezy) by doing the following (all as root): first add the following line to /etc/apt/sources.list
deb-src http://http.debian.net/debian wheezy main contrib non-free
Then run the following commands:
aptitude update apt-get build-dep netatalk apt-get -b source netatalk dpkg -i netatalk_2.2.2-1_amd64.deb
Change the filename accordingly if the version number has slightly changed. With netatalk 2.2 installed, follow other guides on the net (such as this one or this one) to configure a Time Machine AFP share on your Debian server.
This post on Wired editor’s Mat Honan’s blog had me worried. While there are plenty of things you could blame him from doing wrong (mainly not having backups even though the OS he was using makes this extremely easy) the thought of somebody being able to just wipe everything is frightening.
While to my knowledge Apple has not implemented two factor authentication (which, seeing this, they probably should!) a lot of us also have an Google account which is very important to us. Access to a Google account could not only give somebody access to your mail (Gmail) but Docs, Drive and lots of other services as well.
Therefore just don’t hesitate and setup 2-step authentication on your Google account today. Once setup it is actually quite easy to use, especially if you also install the Google Authenticator on your smartphone. To make sure you don’t lock yourself out, print the backup codes Google provides and setup a backup phone (for example of a family member).
Should you ever have to use a backup code or phone, here is how. Also if (like Google suggests) you keep the backup codes in your wallet and your wallet is stolen or lost, you can disable to those backup codes by creating new ones (through Account > Security > “edit” button on 2-step verification > Show backup codes > Generate new backup codes), which as you can see mention specifically “Only the latest set of backup codes will work.”
If you use Lastpass to manage your passwords, you can configure Lastpass to use two factor authentication too using Google Authenticator by following these instructions. While editing your account settings you might also want to increase Password Iterations to 1000 on the General tab. If you signed up a while ago it might still be set to a lower (and less secure) value. You can also restrict access to one country only if you know for sure you are never going to login to Lastpass from abroad.
Finally as backup solution (but not necessarily your only backup solution, as it could in theory be wiped remotely) I recommend Backblaze, which is just $50/year for automatic unlimited backups (works on both Windows and Mac).
