I have an Android mobile device which has Android 2.2 and I want to update it to Android 2.3. What possible ways are there for me to update the OS?
You have two options: If your device manufacturer has released an update, you can use that to update your android. Manufacturer updates are generally released OTA, and they are device specific so you need to check whether the manufacturer has released an update for your device or not. Install a custom ROM.

I would like to use the 3G connection on my android with my Ubuntu. Is there any method to do so?
Easy Tether from Mobile Stream should work. It's a way to share your internet connection with another device via USB. Get the Lite version (does not support https, or tethering to gaming consoles) or the Full version . Supports Windows 7/Vista/XP (32-bit and 64-bit), Mac OS X 10.7/10.6/10.5/10.4, Ubuntu 10.4+ and Fedor...

I've uploaded my mp3s to Google Music. I also physically have the files on my phone. But now when I use the Google Music app it shows the songs on my sd card and the songs I've uploaded to the cloud. Apart from deleting the files on my phone, is there a way to tell Google not to sync songs I already have?
I think that there is no other way as to simply delete the files on your Android device. Make sure you have a copy of the files on your PC or an external HD. I am not sure if one can download the mp3s easily from the Google music cloud. You have the files in Google musics cloud, why do you need them on the device too? ...

Is there an easy way to un-root Android 2.2 on Droid X rooted via z4root? The reason is that I would like to apply a Gingerbread 2.3 update from Verizon, and that update ALWAYS fails to install. Since I never had a custom ROM on the phone, my first guess is that the problem may be due to being rooted, but I don't see a...
z4root added an "Unroot" button in version 1.2. Version 1.3 added "force unroot" (not entirely sure what that means). You can grab the most recent version from the XDA thread , then you should be able to simply hit "Unroot" and be on your way.

When I chat in Google+ through my desktop, my two android devices get the conversations as well. Anyway to stop that from happening? I don't want to necessarily log out of the Apps since I can walk away and I want to still receive messages, but if a conversation is occurring via website, can I have the Apps ignore it?
It appears the message is initially logged to my phone, and tablet, as Google says "Hey there's a new mmessage fofor you." Once I start in on the convo it only runs on the one device.

So we got a Kindle Fire at work today, and I've been playing with it a bit to see what all it can do.

In general it's o...
This appears to have been added in v6.2.2 of the Kindle Fire's system firmware. I updated today and there is now a fullscreen button at the far right of the bottom menu bar in the stock browser. Pressing it hides the menu bar, the status bar, and the tab bar.

There're two flavors of USB ports - powered and unpowered. Unpowered ports can't supply power to the devices and are rather rare. You identify them easily - connect the smartphone to them and see if it starts charging. If it starts charging the port is powered and you're okay.

Yes, it is likely to be the problem. I suppose it's a hack of yours if these apps are on SD rather than internal memory.

According to AndroidCentral and these XDA posts , the Photon 4G is specifically made to prevent access to AT&amp;T or T-Mobile and an unlock code won't do anything.

I just bought a Samsung Galaxy 2, coming from a Nokia 3600. My old cell phone had a quite simple calendar app but when it was supposed to alert me it kept ringing and vibrating until I dismiss it.

Today I used the GPS on my Android for the first time, and I was wondering how it actually works. I know that Android phones have a GPS chip in them, but does the phone establish a direct connection to the GPS server or is there something else going on? If there is a direct server connection, does that mean that every ...
GPS itself does not need a network connection to any server to work. It just needs a signal from a least 4 GPS satellites to calculate a good position fix. There is also the GPS Almanac, which basically provides future data on where the satellites are expected to be in a given time in the future, usually up to 7 days. ...
