Free North American calls and incoming calls on your Android phone.

You will need

• a google voice account
• IPKall number (will explain how to get it)
• a SIP provider (will explain how to get it).
• GVcallback app

1. First get a SIP provider. Some of the suggestions are http://sip2sip.info/ and http://sip.antisip.com/account/register.php. Both are free, but I have not used it. What I used is voipraider, but may need to spend $5 to get the connection activated (you can use the $5 to make calls thru out the world).
2. Download CSIPSimple and register the SIP account created the above step. Make sure that the SIP registration in CSIPsimple is successful and active (the account will show as green and will show in the notification area of Android).
3. Now create an account using IPKall. Provide the SIP information from step 1 and you will be given a free US number. (What IPKall does is forwarding calls to the number (free US number) to the SIP account. If the SIP account is online (in Android), you will get the call. This way you can get free incoming calls on your Android.)
4. In the google voice webpage, add the IPKall number from step 3 (Tip: If Google voice does  not allow you to enter the IPKall number because it's already used, create a new IPKall number). Install GVcallback app on your Android and select the number just added as the number for call back.

That's it. If you dial somebody from your Android phone, an option will come up to dial using GVCallback. Just select that option and you will receive an incoming call. Once you accept the incoming call, it will dial the outgoing call. You can use this method to receive and make calls only using Wi-fi (no need of phone connection).

I am writing about this method so that you know such an option exist. It is your responsibility to understand the terms and conditions set forth by your phone company/google.

Installing CyanogenMod 7 (mil version) ROM on Koodo LG optimus One Android phone (P500h)

Root the phone before doing this.

Download cyanogen_thunderg-ota-eng.mil-6.5.4.zip into your microSD card. CyanogenMod 7 ROM is based on Gingerbread. Install ROM Manager on your phone. Open ROM Manager and select Install ROM from SD card. Now browse to the downloaded cyanogen zip and tap it.

In the menu, check backup existing ROM (if you want to back up the current OS, highly recommended). Check the options to wipe data/cache and dalvik cache. Now Tap OK. The phone will restart and backup the files and then proceed to CM7 installation.

The phone will automatically restart after the installation (takes about 5-10 min). You will see a brand new OS on your phone. Go to settings and add your google account to synchronize contacts, mails etc.

If you want any other google applications which are not already installed with CyanogenMod 7, follow these instructions.

The same procedure can be used for installing any other android ROMs.

Install google apps on your new Android OS.

If you want any other google applications which are not already installed with your current Android ROM (like CyanogenMod 7), download apps-addon.zip. If you don't have it already, install ROM Manager on your phone. Open ROM Manager and select Install ROM from SD card. Now browse to the downloaded zip file and tap it.

In the menu, check backup existing ROM (if you want to back up the current OS, not required in this case for installing google apps). Uncheck the options to wipe data/cache and dalvik cache. Now Tap OK. The phone will restart and backup the files and then proceed to gapps installation.

Rooting Koodo LG optimus One Android phone (P500h)

This procedure will work for LG optimus One Android phone from Koodo (P500h). This may work for other LG Optimus One phones as well, but I have not tested it.

Do not use z4root to root this phone (many people suggested to use this, but didn't work for me at all). The process takes forever without any result.

Download GingerBreak-v1.20.apk (google it, I am sure you will find it). In the application settings, allow installation of non-market applications and enable "USB debugging" in Application settings>Development. Once you install the apk, you will be able to do a "Permanent root" without any fuss.

Please leave a comment, if you have success with any other methods.

If you want to go ahead and install a new ROM (for eg cyanogenMOD 7) instructions are here.

File explorer for LG Optimus one (Android)

What I mean by best file explorer for Android? It should easily navigate to your microSD card. It should be able to access your (home) network contents. This is especially important because this allows you to get rid of the usb cable.

The file explorer which I am using for these purposes is ES file explorer. It is free and you can configure (map) the network drives. Once it is done, just tap the LAN and all the mapped drives will get listed. It is as easy to use as Windows 7 Homegroup. You can play music/movie files in your phone like this. It allows copy/paste from network computer to micro SD card. Really useful software.

Media player for LG Optimus One

The stock media player in Android is just ok. It will not play all video files. If the resolution of the avi file is higher (resolution more than 640x360), it will give an error message "resolution not supported".

However, you can freely download Moboplayer. This is the best player I have tested. They say that it can technically play any file played by VLC media player, since they use the same codecs (FFDshow). Anyways, Moboplayer was able to play the files rejected by stock player. There was no "resolution not supported" messages anymore.

Note: Make sure your video file does not have AC3 audio. mp3 and AAC audio work fine.
