Yes, it is indeed. A major breakthrough since before ZiPhone firmware 1.1.1
always had to be the starting point. Plus the older 1.1.3 jailbreaks,
referred to as "soft" upgrades, were kinda problematic and of course a lot
of work to perform. All that is history now, with the release of ZiPhone.
It's the only way to go.

No, a different method wouldn't help--and in fact would be much worse. The
Mail issue is rare--I have never had and have done 10 jailbreaks via
ZiPhone. But it's a simple fix to get it working should you have the
problem.
The problem with iPhysics et al is not the jailbreak, it's the apps. Prior
to firmware 1.1.3 everything on the iPhone ran as root. You can imagine what
a security threat that would be when SDK third-party apps appear. So now
apps run as the mobile user. Problem is, apps that have not been updated for
mobile user still store their data (like iPhysics levels) in /var/root
instead of /var/mobile. Till the apps get updated for 1.1.3 a quick symlink
will make them work.
Of course without jailbreaking we wouldn't be able to run these apps at all.

I personally install BSD subsystem and OpenSSH first whenever jailbreaking.
I do this because I find SSH/SCP the easiest way to get into my iPhone to
transfer files, run a terminal window, etc. I also use BossPrefs to turn SSH
off when I am not using it.
OpenSSH requires BSD SS, as do other apps--and if BSD is not installed those
apps won't install either. BSD subsystem is an extensive collection of 'nix
tools, pretty much what you'd find on a full blown computer. That doesn't
mean you have to use a command line (but you can), the tools are called by
plenty of GUI apps too.

The reason for the security concern is because many people will just leave
SSH, with the default root password still in place, on all of the time. This
means if you happen to be sitting at a hot spot someone could SSH into your
iPhone and have full control. As I stated earlier though, I use BossPrefs to
disable SSH when I don't use it (and I have changed the default passwords
for root and mobile). For sure you won't need to install it and uninstall
OpenSSH for anything you'd want from Installer.
