Apparently if you want to backup the games data, you need to have a rooted phone and use a different version of Mybackup ie Mybackup root.

step by step on video
or
can try this apps if u like. It can switch off the screen like the crt off animation https://market.android.com/details?id=com.katecca.screenofflock&feature=search_result
Can you please upload what you mean.
I quite like the new animation. Just want to see if it is the same as what you describe.
Also, I updated my firmware over the air. Not sure exactly when it was available. It could have been earlier but been busy lately.
It was quick and easy and also the phone settings and data were preserved
At the first boot it there is a pop up window asking if you want to back up online to Google.
so the only drawback on 2.3.4 is the absence of crt off animation??? i don't know why they are removing such good feature man... what a waste...
yeah its like a bend in and bend out animation....borriinngggg :smileygrin:
also..the keyboard now has bold letters....not cool...
Slimshaddy , since you tried mybackup pro , could you tell me:smileyhappy: ::
*does it save ALL of your apps other than AM ???
*And does it save the data in an app ???
For example; I'm using BI notes app , and I've saved many notes in it . I'm afraid to lose those notes:smileycry: . Please tell me will I lose my notes IF I do the update ?
no it dint save any of the data....for no game 
as apc user said the phone shud be rooted..
also..
download my back up pro..
i have a note appplication "note everything"
and there were many notes
and they backed up 
when u'l click on backup in the application
it'll ask u to backup what thing..
ie applications or data..
if ur note application comes in data option..this will mean all ur notes will be saved 
mine got saved..
but first backup ur applications then go to data..
if in data , ur notes application is not showing then it may not back it up..not sure :+
u shud have told me b4 
lol :smileygrin:
its ok...
but i lost all data of my NOVA game 
uninstalled it 
it seems it has to do witht the game itself too, robotek doesn't require that backup, the game data is stored on the SD card
