This is a a list of Android applications that I currently have on my phone. Some are more often used than others, but all are useful.

These apps are running on my Sony Ericsson Xperia Arc, which has Android 2.3.3 on it. Most of them ran on the Sony Ericcson Xperia X10 as well.

ADW Launcher is a fast and feature rich home application replacement. Use it instead of Sony Ericsson's TimeScape and your phone will feel faster.

As I wrote before, the USA/Canada mobile market is ruled by corporate interests. One of the myths is that there is a shortage of "spectrum". This gave way to auctions for spectrum. In turn this means that different companies make handsets that run on different frequencies, and the balkanization of the market, or prices going up as phones become multifrequency.

Now, Citigroup questions if US spectrum shortage is real.

Hope Canada listens too.

Experimenting with the CyanogenMOD custom ROM on an HTC T-Mobile G1 Android phone, I frequently encounter that the camera would get a "force close" error. After the application exists, the camera app would not start again, unless you reboot.

Since this takes some time to do, and is inconvenient, I found another way to reset the camera without rebooting.

Here are the steps.

1. If you do not have the ASTRO file manager, install it. The link has the QRCode for it.

An apparently useful application for Android is Instant Heart Rate, which can be installed from the Android Market.

What it does is measure your heart rate using the built-in camera of the phone.

On my Motorola Milestone, there was a serious flaw though. Once you use the Instant Heart Rate app, the camera's brightness will be totally off: all your pictures will be severely overexposed (all white).

The Canadian mobile phone provider Rogers has many plans, but many choose the Pay As You Go, since it is suitable for their needs.

The bad part is that the plan does not include any data usage on Smartphones.

But there is a way to get this working on Android phones.
