As now we can unlock Wildfire S Bootloader I tried some ways to permanently root this device.
Gingerbreak seems not to work, however, Zerg rush does.
You either need an S-OFF device OR an S-ON device with unlocked bootloader

There is a VERY EASY way to root WFS now. I take no credits in writing any stuff related to rooting that, I just want to show how you can easily root the WFS and give newbies a first station to come to.
Please come here, and download HTC Supertools by frigid, give him a million thanks, download tools and run the supertools.

Be sure to use HTC Supertool v3 (directly download here:

1) Press 1 (Prep (using zergRush CREDITS to Revolutionary)) and Enter, zerg rush is now run
2) Press 3 (Attempt Perm Root (Must prep first)) and Enter, now the device will get rooted
3) type reboot and Enter to reboot your device.
Afterwards your WFS will be permanently rooted.
If you stuck rooting the device try this:
1) Press 2 and Enter, instead of 1
2) Press 3 (Attempt Perm Root (Must prep first)) and Enter, now the device will get rooted
3) type reboot and Enter to reboot your device.
I tested it with European latest Stock Rom 2.3.5 and HTC-Dev unlocked bootloader. I can confirm that a file could be copied to /system, then I rebooted again and the file was still there.
