1-Click Universal Root

I've not had the guts to press the button yet but there is a new app about that will (apparently) root the following android phones without anymore fuss than sending a txt message.

Google Nexus One (2.2)
HTC Hero (2.1)
HTC Magic (1.5)
Dell Streak (2.1)
Motorola Milestone (2.1)
Motorola XT701
Motorola XT800 (2.1)
Motorola ME511
Sony Ericsson X10 (1.6)
Sony Ericsson X10 Mini Pro (1.6)
Acer Liquid (2.1)
Vibo A688 (1.6)

Unfortunately the following phones aren't supported:
Samsung i9000 (Galaxy S)
Samsung i6500U
HuaWei U8220
HTC Desire / Legend / Wildfire

I'm not one to quible but the fact there is a list of unsupported devices kinda makes the 'universal' claim a bit of an exageration. But hey the Nexus is supported so what do I care (sorry Tim!)?

Install the app from XDA Devs and click the button. You can unroot your phone using the same app.

Reading the XDA thread reveals that rooting your phone this way does not modify the boot loader so your warranty is intact, and you can unroot it so no one is any the wiser!

You can install new recovery images, new roms (like Cyanogenmod), or just root your phone to enable enhanced apps (screen grabs, full backups, etc).

A word of warning. This was on the Android Market but Google removed it as it exploits a vulnerability in the Android OS (allegedly). It is likely that future updates will patch this, but if you've installed a new rom or patched your recovery image this shouldn't be an issue.

2nd word of warning - If you brick your phone doing this or something rooty after doing it, it's not my fault!
