It's not thick at all, don't worry about it.
What methods have you tried? As far as I can tell, the 10e comes with Gingerbread (2.3) out of the box? That means that methods like z4root and Superoneclick probably won't work.
There's also an app called Gingerbreak
. It works for some devices, but not all of them so if you have a read through that thread and see if anyone mentions the Viewsonic.
