As you might have heard AMOLED screens are in short supply. This has forced some manufacturers to switch to S-LCD even for existing models. HTC Desire is one of the affected phones and a side-by-side of the old AMOLED packing Desire and the new S-LCD one show how the two technologies stack up…

Reportedly, most people will have a tough time telling them apart but there are some differences. For example, the image on the AMOLED HTC Desire is more bluish while the S-LCD screen shows a yellow tint.

Colors on the AMOLED screen are more vibrant and it seems brightness is a bit higher than the one of its S-LCD counterpart, which however has a more accurate color representation. The black levels seem pretty much equal, at least judging by the photos.

Still, the S-LCD screen on the HTC Desire has a slight edge in sunlight legibility. It also offers some improved power usage in the general case (though AMOLED gains an advantage if displaying mostly black images). LCD screens consume less power when displaying all-white content.

Windows still dominates the netbook market despite various attempts by Linux distributions to push it out. But just because you didn't succeed at first, doesn't mean you should give up. MeeGo for netbooks, for example, sounds great , but it's not ready yet. So Jolicloud will try to use its hesitation in its favor and find its place under the sun. The OS that tries to appeal to users and manufacturers alike with out-of-the-box thinking just reached version 1.0.

It’s based on Linux though it tries to leverage on HTML5 and the cloud with a pinch of social networking for taste. Apps you’ve installed automatically get synced between the multiple devices you use, you can “Like” apps and your friends will be notified (here’s where the social networking comes in) and Jolicloud will take care of backing up your data to the cloud and installing the latest browsers.

Jolicloud comes with a pretty broad selection of apps and services – Firefox, Gmail, Facebook, Twitter, Spotify, Boxee, Hulu. The OS features a Universal File System, that is it’s easy to manage your data whether it’s stored locally or in the cloud (Jolicloud supports box.net, Dropbox, and drop.io and new services are added).

You can check out the Jolicloud blog for more info if you’re interested. Some of the current Jolicloud users have already been invited to upgrade to v1.0 but if you didn’t get an invitation, you can check this link where several invites are handed out daily. By the end of the month all users should be updated to v1.0 and the ISO images and Windows installers for Jolicloud 1.0 should be ready soon too.

Samsung Galaxy S made it to Brazil and it seems that along the way it has picked up a strange appendix pointing from its top. Yup, it's a digital TV antenna. Unlike the other Galaxy S versions spread around the globe, the Brazilian Galaxy S comes with ISDB-Tb Digital TV on board. Oh, and it's pretty overpriced.

As for the rest of the features, you should be familiar with them since those are common for the Brazilian and the non-Brazilian Galaxy S variants. So, you'll find the same gorgeous 4-inch Super AMOLED touchscreen of WVGA resolution as well as the 5MP autofocus camera on the back which is capable of shooting HD videos (720p@30fps).

The Galaxy S is powered by a fast 1GHz processor and packs an impressive1500mAh battery. At its launch the Brazilian version will run Android 2.1 (a.k.a. Eclair) but an official Froyo update should follow up pretty soon.

The only downside of the Brazilian Samsung Galaxy S is its price. The SIM-free handset said to cost good 2400 Brazilian reais (around 1036 euro). Hopefully, the Brazilian operators will offer a better subsidized price at the launch of the phone (some time in September).

HTC hearts Android. They've released a lot of droids but still have unannounced phones - the HTC Fiesta and Paradise will pad HTC's portfolio with even more Android. The HTC Paradise seems like an Aria with a QWERTY, while the HTC is a bar touch phone.

Found, believe it or not, on Craigslist, those two AT&T samples have only surfaced before as names from UA profiles. Not much is known about them now either but at least we can get a good look at them.

The HTC Paradise is likened to the HTC Aria (which until recently was AT&T exclusive) so it should have similar specs with the obvious difference of a slide out QWERTY, a form factor HTC has neglected recently.

The HTC Fiesta on the other hand has a 3.2MP camera, which suggests that it will be a low-end droid. There are some concerns that the Fiesta may have been canceled so it might never see the light of day.

Anyway, there's a good chance that if these phones do come out, they'll be available on AT&T, but we wouldn't be surprised to see them on other carriers as well.

Many people are curious to know how much data FaceTime over 3G actually uses. We put two iPhone 4s to the test, one running FaceTime over 3G, and took before and after screenshots of the data. As you will see, if you do the math, a 5 minute FaceTime call with lots of movement used 14.7 MB of data. That's about 3 MB per minute.

That's not too horrible when you consider some streaming services use that much just to feed you video of England embarrassing itself in global football tournaments. Then again, we'd be remiss not to note that Fring does it at a claimed 1MB a minute and sans the jailbreak
