OK, I dont understand the lingo. First, ME, I have 40 years programming experience and computer design experience. But about Cell Phones, I know nothing. Second, my phone,I have a DX that I have rooted (Z4root), overclocked (Droid 2/x), teathered, and loaded the JRummy ROM using Clockwork Bootstrap. I did all these by just following instructions but not really understanding what I was doing. Now I would like to experiment with some more ROMs, but I keep running into terms that worry me when the text associated with the term says scary things like...."this might brick your phone". I know what brick means and it aint good so I really need to know what, sbf leak and 2.3.320 mean. I am sure there are others, but for now these three would help. Where can I find info on these? I did a search on sbf and SBF and neither one returned any results.
