Mozilla has announced they have released Firefox 4 for Android. It’s also available to download for Maemo devices. Mozilla says that Firefox 4 is up to three times faster than the stock browser in Android, so that is definitely good news.

There are also major enhancements to the JavaScript engine, which is designed to make sites load faster. The mobile version is built using the same technology as the desktop version, and offers tabs, one touch bookmarking, and a whole bunch of browser controls. Sounds awesome. We can’t wait to try it.

Thanks to an internal corporate memo, we know that Apple is planning a deal with Radio Shack. About 500 stores US-wide are due to start carrying the iPad 2 on Tuesday, March 29. This is apparently a last-minute plan that had only been agreed upon in the “last few days.”

The company had a much wider launch with the iPad 2 than it had previously. Usually Apple waits until supply shortages have settled down or until it gets closer to the holidays, when the expansion can have a maximum effect. The more aggressive launch is likely due to battling Android tablets like the Motorola Xoom.

Amazon has added new feature to their Android App Store that now allows you to try applications before you buy them. We can all appreciate that. We will get stuck with fewer apps we don’t like. The feature is called ‘Test Drive’. It’s an online emulator that allows you to try the Android app within the browser. This gives Amazon an edge against Google’s Android Market which doesn’t have a feature like this.

The new ‘Test Drive’ feature is only available to users in the US right now and it does have some restrictions. The service is also not available on every app in the Amazon App Store just yet. It’s only available on a few hundred apps, but more are being added as we type.

Last week a new version of the HTC Flyer was announced for the US, the HTC EVO View, a WiMAX enabled version of the Flyer that will be available with Sprint in the US. But now we have word that the HTC Flyer will also be headed to T-Mobile some time this summer.

The HTC Flyer packs in a 7 inch touchscreen display with a resolution of 1024 x 600 pixels, a 1.5GHz Qualcomm processor and Android 2.4 Gingerbread. It has two separate camera’s, a five megapixel version on the back and a 1.3 megapixel camera on the front. Other features include a 4,000mAh battery, 3G and WiFi.

We’ve had Google Android phones since late 2007 and the first Google phone came from working with HTC on the Google Nexus One which launched last year. This year the Google Nexus S arrived from Google and Samsung. So they like to partner up. The latest rumor is that Google is working on its first Nexus-branded tablet with another friend.

According to Mobile Review, Google is working with LG on a Google Nexus Tablet. Of course this tablet will run Google Android 3.0 Honeycomb and it might launch as early as this summer or early in the fall. It is likely that Google would make sure that the tablet would get software updates earlier than third party tablets.

ASUS’ new Android tablet, the Eee Pad Transformer, is headed to the UK on March 30th. The device should cost between 379 GBP ($606) and 399 GBP ($639), depending on the amount of storage you choose. You can choose 16GB, 32GB or 64GB capacities.

The Eee Pad Transformer features a 10.1-inch 1280 x 800 capacitive touchscreen display, a 1GHz NVIDIA Tegra 2 dual-core processor, 512MB/1GB RAM, 16GB/32GB/64GB of internal storage, a microSD card slot, a 1.2-megapixel front-facing camera, a 5.0-megapixel rear-facing camera, and an optional full QWERTY keyboard that turns the tablet into a notebook style PC and runs on Android 3.0 Honeycomb.

An HTC representative says that the Thunderbolt should get Android 2.3 in the spring. We know thise because the representative named Carol was telling Droid-Life reader John about compatibility limits with Bluetooth, when she added that HTC was “excited to announce” the refresh. She says that more details would come closer to the launch.

Among the list of features mentioned were NFC and interface polish changes. This isn’t very surprising since most of HTC’s new phones will all launch with Android 2.3, but hey it’s always nice to have confirmation.

Acer will be launching two of their latest tablets, the Iconia Tab W500 and the Iconia Tab A500 in Europe on April 8th. Both tablets start at around 449 GBP (or $720).

The Iconia Tab A500 features a 10.1-inch display, an NVIDIA Tegra 2 dual-core processor, dual cameras, 1GB RAM, 16/32GB of storage, 3G, WiFi, Bluetooth 2.1, an HDMI port and Android 3.0 Honeycomb. Your wait is nearly over.

If you are an Android user, we have some good news. Google has announced that testing of Android’s in-app purchasing system has officially begun. A full roll out is planned for next week. Android devs can now add in-app products to their software that is currently available, set prices, and set up a test account to make sure that the entire process works smoothly for users next week.

Google had said that in-app purchases were coming last month, so devs have been waiting patiently. Are you going to take advantage of in-app purchases when it goes live? It should be a better way to upgrade apps.

HTC announced their latest tablet yesterday, the HTC EVO View 4G. It’s a WiMAX enabled version of the HTC Flyer Android tablet. And now Best Buy has announced that they will begin selling the HTC Flyer WiFi Android tablet this spring. To refresh your memory, the HTC Flyer comes with a 7 inch touchscreen display with a resolution of 1024 x 600 pixels.

The HTC Flyer WiFi will have Google Android 2.4 Gingerbread, a 1.5GHz Qualcomm processor, a 1.3 megapixel camera on the front for video chat and a 5 megapixel camera on the back. HTC hasn’t announced official pricing on the Flyer WiFi Android tablet yet, but hopefully we will know soon.

AVG has launched AntivirusFree for Android tablets, called AVG Mobilation for Android. It uses a cloud based security platform and AVG says that the app will not kill your battery life, which is good news. It will have the ability to scan other apps, settings, data and media files for viruses. Basically it does what it does for your PC or laptop.

There is also a remote wiping facility in case you lose your tablet and an option to back up to an SD card. The AntiVirusFree app is available to download from DroidSecurity.com for free, while AntiVirusPro costs $9.99. It’s worth the investment since we have so much of our lives on tablets today.

So now the Samsung galaxy Tab 8.9 is official and we have some official press photos and more detailed specs. The Samsung galaxy Tab 8.9 measures just 8.6mm thick, making it an uber thin and sleek tablet, thinner than the new iPad 2 even. It weighs just 470g and comes with Google Android 3.0 Honeycomb and a custom Touchwiz UI from Samsung.

Other features include an 8.9 inch display with a resolution of 1280 x 800, a 1GHz dual core processor and it will play back full HD video in 1080p. There’s also a three megapixel camera on the back and a two megapixel camera in front. Two models will be available: one with Wifi and one with WiFi and HSPA+.

This shot taken from CTIA by the guys over at Pocketnow shows off some Samsung Galaxy Tab 8.9 promo material. It may not be the actual device, but it’s almost as good and gives us some info. Looks like it’s comprised of the Live Panel homescreen with custom widgets, and an app switcher for BlackBerry PlayBook-like app switching with live previews of the apps that are open in the background.

This image also tells us some of the specs. It sports an 8.9″ display with 1280×800 resolution (that’s a higher pixel density than the Motorola Xoom). It’s very thin too at just 8.6mm, and will weigh just 470 grams. And the CPU onboard is a dual core 1GHz chip.
