Android HTC - Hacking explained
Background:I tried to root and "S-OFF" my HTC Desire and it resulted in the phone not booting anymore Having no experience in the Android hacking field at all, I was pretty much stuck, and then there's only one thing to do: Google up.
As I spent the next 4 hours getting a basic understanding of how Android phones work and what the different hacks and tools are, I needed a way to keep notes. Notepad wasn't going to cut it and I figured that a more 'attractive' method may serve as a good reference for other people who are interested in Android hacking. Adobe Illustrator it was.
I managed to get my phone working again but continued googling and asking smart people stupid questions to keep getting a better understanding of the subject. At this point I've learned everything that I wanted to learn. Not that I'm an expert but I know just enough about everything to fool others into thinking I am one I'm making the information public, if there are errors or omissions please inform me and I'll fix it.

Also, at least on my Motorola phone, /system is a different flash chip, and therefore the main filesystem cannot be repartitioned because the partition is physically separated from the data partition.
You also say the dalvik-cache is similar to the Windows registery. This is not true! Try wiping your Windows registery and then rebooting. Dalvik-cache stores optimized application code (and some other stuff), if you wipe it, your Android device will take a long time to boot but it will boot eventually. Also note that read activity does not wear out SD card memory (as your statement "Since there is a lot of read/write activity towards this cache, it may wear out your SD-card prematurely." suggests)

good to see all this info nicely formatted in one place.
Did you manage to fix your phone?
My HTC desire is currently being fixed, overheating problems
Yeah I managed to install Cyanogenmod 7 on it, and am using it with S2E... But I already have two reasons to re-install: There's a new version of Cyanogenmod that contains a security fix, and I want to try alpharev again (which broke the phone the last time) and resize the partitions.
And a colleague of mine with the HTC Desire also has overheating problems, seems to be battery related: he got his overheating & rebooting Desire replaced but kept the same battery, and in the 'new' Desire (worked fine) the battery died so now his phone is broken again.
I thought JPG would offer better compression but I'll see about PNG
Putting it on XDA-developers is a good idea, when the suggestions are processed I'll make an account there and link it.
