Thanks jujx.
My 3G data is normally off.
Does this mean that when I want to use A-GPS for Papago X5, I must enable data and tick "use wireless network"?
If I just tick "use wireless network" without turning on the data, the A-GPS is not functioning? Is this understanding correct?

Thanks Jason for replying. I understand that by ticking "use wireless network", the GPS will lock on faster etc. What I would like to confirm is when I tick "use wireless network", do I have to enable my data connection? (My data connection is normally off as I am using offline GPS like Papago X5. I am not using Google navigation.)

Yes, it's proven HERE

oh , i forgot got unlock pattern, maybe i should rephrase my question

what i meant is, after ending a call, the screen won't turn off by itself
is it suppose to work in this way? cause in the past when i was using nokia, if there's an incoming call and i've ended it, the screen will goes off and keypad is autolocked

I just tested this. I called a friend, spoke for 10 secs, then he ended the call. Without touching my phone buttons or screen, the screen went to pattern lock screen and turned itself off after 30 secs.

Maybe the behaviour is different if I was the one who ended the call instead..

I just tested again, I called my friend, we spoke for 10 secs, then I ended the call. The screen stayed on longer but eventually turned off. When I pressed the power button to turn the screen on again, the lock pattern prompt appeared.

hey sifus, got a couple questions here.

1st ones. how to change the setting for the Bluetooth to be visible without that annoying 120 seconds ?? i want my bluetooth to be on without that lousy timer...

2nd question...is there anyway to get a custom notification sound like for video caller ringotone and audio caller ringtones?? it seems like i couldnt change the cutom SMS notification?? help!

oh one more...any good app for blocking from data charges when im going to overseas??? really need that so it wont sucking up my credit for roaming!

like using wireless headset? bluetooth need to be turned on right?

ahh ringdroid. thanks!

what about application that block from sucking up our data charges?

Just turn off 'data roaming' under 'Wireless & Network'. Another option - do try out the 'Data Controller' app from the Android Market.

that what he ask for. but the APN also could do it
