root

You can root a Sony Ericsson Xperia Arc from Rogers (Canadian mobile phone network), using the zergRush method.

The method works for Xperia Play and other models as well.

For this, I used an Arc running Android 2.3.3 Gingerbread.

Using Windows

Follow the instructions on the above page.

Using Ubuntu

1. Download the package.

wget http://ubuntuone.com/7mD63kpsKzGmaou5hcftBV

2. Rename the package.

mv 7mD63kpsKzGmaou5hcftBV zergrush.zip

Update 2011-09-02

For the Xperia X10, when upgrading the software using Sony's PC Companion, you will get full Arabic support on the phone, with a beautiful font, and no glitches. The only drawback is the phone is unrooted, and therefore you lose functionality of apps that require root (e.g. Titanium Backup, ShootMe), and have the bloated apps that autostart (Timescape, Moxier Mail, ...etc.)
