Tools for developing J2ME applications
¤¤¤
I have just added a short description of which tools to use for developing J2ME applications. It changes all the time what tool configurations I prefer the best. At the moment it is Eclipse with the J2ME plugin from Nokia.

How fast is your Symbian Code running
¤¤¤
If you want to know how fast your programs or algorithms are running in Symbian you can use the following methods.
TInt t1 = User::TickCount();
// Do something
TInt t2 = User::TickCount();
TInt diff = t2-t1;
One tick is different depending on which phone you own.
To get the tick count on your phone you can call:
User::LeaveIfError(HAL::Get(HALData::ESystemTickPeriod, period));
For the Nokia 6680 it is 15.625 microsecond pr tick.

Symbian Introduction Tutorial
¤¤¤
At the moment I think that there are very few good tutorials on the net that helps you get started programming in Symbian. How do you get started and how do you get to know the basic that will help you move on to some more advanced features.
Yesterday I held a one day tutorial at Berkeley about programming Symbian mobile phones. Some of the material is online and should help others in getting started with Symbian.

Is it a good idea?
Are Nokia hoping that a lot of other people are going to develop the software for it?

Image format supported by 6680
¤¤¤
The new 6680 phones has two cameras. However, it only supports capturing images in specific format. If you try to capture images in a format that is not support an error will occur.
The following format are supported (in Symbian C++):
Back camera: 1280x1024, 640x480 and 160x120
Front camera: 640x480 and 160x120
When it comes to video both cameras supports 176x144 and 128x96
Besides the normal color format the back camera also supports EFormatExif

Vibrator work on series 6.0 phones
¤¤¤
It seems like Nokia finally implemented the vibrator API on the phones.
I have tested it on the 6680, but it should also work on 6630 and I guess it will be standard on all the future series 60 phones from Nokia.
Here is the code that does the trick:
CVibraControl* vibra = VibraFactory::NewL();
vibra->StartVibraL(10000);
Remember that the vibrator function has to be switched on in the current selected profile for this to work. E.g. Tools/Profiles/Vibrator On.

New Nokia Phones Introduced
¤¤¤
Just as The 6680 and 6681 phones hit the street Nokia announced their new series of phones the N-series.
It looks like the N-70 is just a newer version of the 6680.
The N-90 looks like it is dedicated to recording pictures and video,
but the N-91 is the most interesting, that is an online version of an mp-3 player, with Wireless LAN, WCDMA, 4GB hard disk and Symbian OS 9.1.
