Sad to hear that you have the worst experience in Nokia.
I am happy with my N82 eventhough I did not ahem my phone for those ahem applications.
And I love the users here for giving tips.

Could it be some applications running and need to connect to WiFi?

Nokia Service Center latest version is V30.

The N82 has GPS built in, so no need to buy any external devices.
You can use the Nokia Map that comes along with the phone. But you need to pay for subscription for the voice navigation (that means there is voice to tell you turn left or turn right).
Many users tend to install Garmin into their N82. Garmin has better features than Nokia Map.

A-GPS is Assisted GPS.
It is like a "fire starter".
Assume you want to start a fire for a BBQ, you light a match to fire up the charcoal. It will take some time for the charcoal to burn. This is = GPS take some time to lock in the satellites.

If you use a "fire starter" on the charcoal, the charcoal will start to burn faster.
This is = A-GPS faster to lock in the satellites.

So for N82, A-GPS is built-in to assist in locking the satellites faster, but it make use of mobile phone operator signal.
Therefore, when you use A-GPS, you will be charged a small fee by your mobile phone operator.

Only A-GPS lock in the satellites faster. After that it is the same.

If you are driving, then it is not loud enough. But if you are in a quiet room, then it is loud.

Sometimes when I use the speaker, I put it in my shirt pocket. Nearer to the ear and mouth.

I have the SE Bluetooth headset. But sometimes forgot to bring along, then have to use the speaker when call comes in.
All Bluetooth headset battery can last for many days (with one charge).

Probably the technician did not do a good job for you. Go back and ask him to rectify it.

For me, I will go for the original set. Unless the AP set seller is your very good friend.

You have the advantage there. For many of us, we don't have such advantage. If we have this advantage, we will go for AP set like you.

This is very good of you.
When I want to get another phone, will definitely give you a PM.
Hope the shop you go to is in Klang Valley.

With V20, I find that the GPS lock in to the satellites in more than 2 minutes.
With V30, the GPS lock in time is around 45 seconds.

Does this really work? Anyone tried removing the files as described above?

Highlight your problem again.

You can buy those stand where people use to display those pewter plates or photo frames.

This is called a hot pixel. This particular pixel is weaker than the rest of the pixels on the screen. When the current passes through this pixel, it gets hot faster than the rest. That is why it is brighter than the rest.
Not sure how to cure it on a mobile phone.

Anyone tried Nokia Map 3.0 (Beta)?

You can check it out HERE.

Which version of Malsing map is free? I noticed their free map is dated 1 Jan 2008 (which is more than 1 year old).

I thought the red light is use to assist the focusing.

Both his photos are with flash. Not sure why still can see the reddish light.

I agree with you Eve. Mine also don't have the red tint.
