Same here, my battery life is about 2 to 3 days now. Turn off 3G connection unless you wish to use it and turn off after use. Turn off ALL auto update as well.

I'm not sure bout others, further comments are based on my personal experience on my device. At first the battery couldnt last very long. But after a week+, I feel the battery lifespan increased significantly. A full charge can last me for about 3 days (with the usage of BSB tweak). Perhaps u can try installing BsB tweak (if you havent).

You can download the Asian official rom  ( I assume you bought in Msia ) here : http://forum.xda-developers.com/showthread...=577717&page=21 at post#203.
Other rom versions just search around this weblink at the front pages

Yesterday HSPL was released http://forum.xda-developers.com/showthread.php?t=611433; with it you can now flash new radio. The HSPL process is also very easy

This morning I use HSPL to flash the Turkish rom ( so far is only official rom with latest radio 2.06) ; then I continue to  reflash the Topix cooked rom. So my HD2 is now on Topix 1.1.2 and radio 2.06
You need to download first Leo custom RUU to flash rom after the hard SPL is done : http://forum.xda-developers.com/showthread.php?t=575524

The attached cab allows you to disable/able 3G connection. Does not effect anything except 3G connection

Download and rename file from CommManager3G.txt to CommManager3G.cab and use.

hey there ... I've have that cab too but at times i still see G sign  but most of the time is E

Did you start Comm Manager and disable 3G connection? If so, "G" should not appear at all.

Pardon me if I'm mistaken... but I believe G is for GPRS, E is for Edge and H is for HSDPA (3G)

SSPL wont mess up any thing in ur rom since it is only a software SPL, it will retain all the ori SPL (rom ver when u do a 3 color screen)
which is diff then HSPL where it will change the SPL .... SSPL is easier to do since it is only involved the sw layer

... in a nutshell

still thinking of cooking my own rom .... but still no free time

Flashing is easy - just follow the steps , pretty straight forward

Precautions : REMEMBER to take out SIM card and micro SD card to avoid motherboard kena fried. It happen to me before one time in my previous Dopod U1000 ; that time I was upgrading official rom - so was able to claim warranty and HTC Spore replace the motherboard free of charge

For the HD or any others - you must restore back the SPL and also radio ( if is changed )  not only the original rom. First thing SIS or any authorised dealer do is go to bootloader mode ( tricolor screen )  to check the SPL version. Many people forget to do this step and think by restoring back the original rom is good enough. I have help 2 friends claim warranty by restoring back the stock SPL and stock rom - SIS cannot detect there is a rom change before. And also make sure you are restoring back the actual rom not any other official rom ; so before you do any rom cooking write down the original rom version and download a copy of first for possible restoration purposes

Thank you guys for giving me the tips . What i know from early after we flashed the SPL and we can't get it back to original.
What the pda expert guy told me. 

Okay, I've got Topix 1.1.2 up and running... anybody found out how to add chinese support for them custom ROMs?

The PDAexpert guy if he tells you that should be rename PDAunEXPERT. I have done it twice for my friends on their HTC HD and TP2
