I've had enormous fun this afternoon learning about the ins and outs of Samsung's Blackjack phone... and more importantly, what I can change inside its software to do cool things.
The best bit (and most complex) by far has been overclocking. That's right, overclocking a PDA :) The device runs at 180mHz, but it runs quite happily, from all accounts I've read, at 240mHz. I had to run a little utility to completely unlock the device (it seems it was locked down from running applications like this)... but once that was done, it was simply a matter of running this little overclocking app, picking my clock speed, registering it, then doing a soft-reset. People have said that it makes a massive difference - so much so, they couldn't go back to the original speed. My experience was nothing instantaneous... but I guess menus and such are a bit quicker. It might be clearer over the next couple of days.
Then there's a bunch of little things - like shrinking the IE font to fit more on the screen, doing a memory defrag in realtime (!!), increasing come cache sizes... all these things are just registry changes in the phone. Pretty simple when you think about it. Sorta dangerous... but still awesome.
The next challenge will be to see how far I can overclock this. I've read about a couple getting close to the 300mHz mark. I guess I'll know to stop when it starts smoking...
update: lesson #1 when overclocking a PDA... Don't leave said overclocked PDA in your pocket. If it wasn't going to overheat by just overclocking it alone, it sure as hell will overheat when you don't let it breath :)
