Flash to 2.3.3 or custom rom?

Yes, flashing wipes your data. For backup you can use Titanium Backup.
You can use Odin_v1.3 or 1.7.
Flashing is an easy thing, but you have to pay attention what and from you flash.
E.g.: If you upgrade from Froyo to Gingerbread, you have to download the bootloader version instead of a normal one, because Froyo has another bootloader, than Gingerbread.

I used Darky's (From 9.2 till 10.0 Final step by step updated) for 4 months.
The ROMs were very good, but I wanted to get new a ROM, because Darky's ROM is a bit simple regarding flashing, setting for me. Darky's ROMs based on Froyo and Gingerbread (2.3.1-2.3.3) developed by Samsung. I have been on CM7 (2.3.4) for couple of days. This based not on a Samsung ROM. This ROM is said to have a lot of bugs, but the menu is fantastic and the performance,too. If the menu of Darky's is 100%, the menu of CM7 is 180%. Really!!
Being on this ROM I'm not bored.

Mine was fine with 10.5 but not with 10.6. Having said that I have tried the latest version of 10.6. but then again it all depends on usage doesn't it! if u r a heavey user obviosuly your battery wont last.

Anyhow, How did u get on with jiuce defender?

I have only just had time to set it up today, but I will find out soon. 


Services currently running are Settings, DoubleTwist JuiceDefender, AdvancedTaskKiller, DRM content, Software update, Task Manager, Maps, SNS, Google Services, Email and Swype.

What Task Killer would you suggest? I tried the Memory Management suggested by Juice, but I did not understand it so I uninstalled it.

"(Maps, Software updater are dangerous)" When you say this, do you mean it is dangerous to stop it or do you mean it is dangerous because it drains a lot of battery?

Kill: Maps and Software update >>> huge battery drain.
I don't use Task Killer.
"Autostarts" from Market is very usefull. Install it!

In the first round scroll down to Maps, tap on and tap on "After-Startup" and choose "disable", and disable the others,too.
Then scroll down to Software update and disable all.
That's all.

BLN.

Colornote??-I don't use it.

Why do you need to keep your memory 'fresh' (whatever that means)?

There are various articles about this around the web (sorry, haven't kept any links).  The gist of it is that Android is already managing memory in a very efficient way.  Just because apps are loaded into memory doesn't mean that they're using the CPU (which is what uses power) - they're mostly dormant.  What this means is that, if you want to use one of those apps, Android doesn't need to load it into memory (as it's already loaded) - it just has to be woken up.  This is much more efficient than frequently unloading and reloading apps.  Don't worry - if memory gets low, Android will unload some of those dormant apps to make room.

If you run a task killer, then you get extra power consumption because:

• The task killer itself uses power
• The system uses power when unloading the 'killed' apps
• The system uses power again to load the apps next time you use them

There are also a number of apps that are configured to be restarted if they are killed (e.g. Maps), so using a task killer on those does absolutely nothing except consume power!

The only time it's worth using a task killer is if there's a 'rogue' app that won't go to sleep (i.e. it keeps using power) and it's not an 'auto restart' app.
