Hot on the heels of this morning's full and permanent G2 and Desire Z root, XDA-Devs members (apparently headed by grankin01) have released a similarly full and permanent root for the T-Mobile myTouch 4G. In fact, the method is very nearly the same, in grankin's words:
With the G2 already getting a non-persistent "soft-root" solution, it was only a matter of time before someone combined it into a nice, user-friendly package. Stepping up to the plate (or rather, the crease) is Paul O'Brien, the founder of UK smartphone website MoDaCo, well known for a myriad of clever hacks.
Superusers, you can haz them
Deriving its name from the HTC Vision device codename, VISIONary is a simple one-click temporary root app for the T-Mobile G2.
