I totally understand.
And I'm totally grateful for all the links you have provided -- you're certainly under no obligation to do anything more for any of us.
.... that said, here's where I'm sitting: I've flashed to .232 and did so without considering the possibility that getting back to .905 wouldn't be as easy as getting to .232 was.
I see where you've included RSDLite and the full .905, and dfib has conveniently linked to a post as to how one would use these things to get one's Bionic back to .905, so that's good to go.
... although, again, with my own personal level of stoopid, I had not considered that coming back would lose all my data (which isn't on the SD card). (Not that I wouldn't have pulled the trigger on .232 anyway -- the data drops were making me desperate.) In any event, reading that HoB (at least, at one time) had a way of going back without losing data made me think that, yeah, that would be ideal. (Reading the HoB link now makes me think that, yeah, it's morphed into something else and isn't really for me.)
At this point, I'm pretty much weighing the options of (a) data loss versus (b) just staying on .232 until my contract expires. I mean, just how much better is the actual release of ICS going to be?
[rant]And why do they have to make it so damn difficult to go back anyway? And what's up with apps that don't save data to your SD card?[/rant]
