Under "Droid Hacks" forum, there is a post concerned me a lot, see here:
I want to know from those brave, with 2.2 rooted phone in your hand, do you experience any issue after getting 2.2 root? Here are my questions:
1. If you OC the cpu, is the performance improved substantially? If so, in what sense?
2. Can you do usb tethering with frf84b build? Or you have to use frf57? Is the connection stay stable?
3. When you do wifi tethering, do you experience drop connection problem at all? Any security concern?
4. Do you experience any signal, call quality related problems? Please explain.
I would really appreciate your sharing of information, if possible.
