I have a rooted phone with the stock ROM/Kernel. I only use the tethering hack outside of the stock ROM. I was prompted with "System Update" this morning. Should I stay away from this update, or would it be ok? Thanks!
A system update will most likely un-root your phone, but if all you have is the tethering hack, I would recommend updating, re-rooting, and reinstalling the hack, after making sure the the hack is supported in the next version.
