Even I am waiting for some good efficient custom ROM.

Well, everything about Odin is perfectly described in the first post of the topic, which I gave a link to.
I only added details about things that were not fully described.
I forgot something ; sometimes, the phone puts itself in USB Modem mode and I'm not able to revert it. You can do an hard reset to revert it (but you lose your data) or you can reboot the phone in recovery mode
(same thing that when you root your phone ; press Home + Menu + Volume + Power to start the phone (probably Volume down + Volume up, not sure, try different combinations)) and decide to reboot the phone, one of the options that you can select in recovery mode
(don't forget that this applies only with flashed firmware, if you keep Orange's one, you can only do a factory reset). This fixes the USB problem (even if it can occur again). A normal reboot fixes nothing, you have to use Recovery mode to fix it, even if you simply use it to reboot the phone.
However, a few posts ago...
1. Dial *#7284#. This should open app called PhoneUtil (there are other ways to get to it)
2. In USB section, swith it to Modem, then switch it back to PDA
3. Exit, and USB should work.
I'll try this if the problem occurs again, it'd be faster than a reboot. I'm also using AdbWireless and it works well without any USB connection.
Oh, and I tried the GPS outdoors. It is incredibly slow
when you rebooted the phone, I got a fix only after several minutes, but once locked to a GPS signal, you can disable GPS/Wifi/3G/Anything or shut down the screen (not the phone), when you enable everything back, you get located very quickly. I wonder if there's a way to improve first fix delay though.
I've been told that task killers were completely useless and not productive, this was said in this topic too. So I removed my task killer and installed Watchdog.
I installed Swapper 2 to use a linux-swap on my SD card (I formated it with Gparted), it works (even if no one can tell if swapping is useful on Android devices).
I'd be interested in overclocking too. I know you can do it only with a custom ROM because it's a very low level change...I'm using SetCPU to underclock my device when needed and it works fine (I strongly advise you to buy this app, so you can slow down your CPU while screen is off and/or battery is low), it'd be better with some overclock when needed, though.
Now I will try Live Wallpapers. No reason for them not to work though, as some of you said they were working.
