I'm running 1.05 but thanks for the tip.
I'd be wary of that package, personally:

I'm not saying it does cause hangs on dictionary use, but I've had a T1 that hung like that (I bought it used), and I've heard of others with the problem.
On a partly positive note, since rooting, the standard Sony reader now displays percentage read and a clock at the bottom. That's a big improvement for me.
Thanks to all the people who made the rooting package available.
