RIM’s official Twitter client has been lingering around the internet for around three months now as a public beta, but only just recently lost its “beta” tag. If you were holding back on downloading this app because of fears of instability, fear not. Since this release of the app theoretically is the golden version of the software, it means that some bugs and other glitches have been flattened out into a solid release and that you can get on with your high priority business (or casual business) without any fears of the app failing on you and exploding your phone into millions of pieces. But since the beta didn’t do that to you, we’re going to go ahead and assume this version won’t either. If you have BlackBerry OS 4.5 or later, you are now free to download the app through your BlackBerry web browser or the BlackBerry App World.

The iPhone 4 was launched today to eager, eager crowds. But how does Apple’s new smartphone compare against other phones that want a piece of the action? BillShrink has taken a look at the total cost and features from each of the current top phones of AT&T, T-Mobile, Sprint, and Verizon.

And, as it turns out, the iPhone has the cheapest costs over a two year period.

Although Apple’s iPhone might be the cheapest under contract, it’s important to note that AT&T is the only provider in the chart above the restricts data. All the other providers have an option for unlimited data. AT&T provides 250MB for $19 and 2GB for $25. Want tethering? That’s an additional $20 per month.

The iPhone Dev-Team has released a jailbreak of iPhone OS 4 beta 4 (redsn0w 0.9.5b4) intended solely for developers of jail broken applications. Since this release is only meant for developers, this version of redsn0w only works with Mac OS X and iPhone 3G devices that are registered with Apple’s developer program.

If you meet those requirements, and you’re willing to risk bricking your iPhone, follow  how to jailbreak iPhone OS 4 beta 4 after the break.

Steps 1 and 2 are only if you are not using a beta build of iPhone OS 4. Skip them if you have iPhone OS 4 installed on your device already.

Step 1: Activate your UDID with a Apple developer account to install iPhone OS betas. You will be stuck at the Connect to iTunes screen forever if you ignored this step.

Step 2: Install iPhone OS beta 4 (Beta 1 will still work, but isn’t advisable) by Option + left clicking on ‘Restore’ and selecting the beta firmware once prompted.

Step 3: After you’ve finished installing and syncing your iPhone again, open redsn0w (download can be found at the source link below) and click browse on the first screen. Navigate and select your beta firmware that you used to restore your phone. From this point on, it should be very similar to how you jailbreak on iPhone OS 3 using DFU. Follow this guide for more instructions.

Step 4: You should be done! Cydia should be there, but with a white icon and no repositories added. Add the following repository to use the standard sources and get the normal icon back: http://apt.saurik.com/cydia-3.7

There’s no denying that the number of complaints about the Nexus One’s 3G have been numerous. Now, after several updates, Google says “we are no longer investigating further engineering improvements”. Google feels that the patch they supplied took care of most of the problems, and you’re stuck with whatever bug you have now. In short: Google isn’t fixing your Nexus One connectivity problems anymore.

Ry Guy, a Google employee, posted on the support forms:

Original iPhone adopters may have felt left out when Apple confirmed that there will be no more support for their model, including no iPhone OS 4,  but those very same users can rejoice knowing that Android in all its goodness has come to the original iPhone. Using OpeniBoot, it allows users choose to load between the standard iPhone OS or Android. It’s not perfect, but kinks will soon get flattened out and there’s also hope that it will soon be implemented in the iPhone 3G and 3GS.

Early adopters, get ready – Walmart has begun to sell the HTC HD2 on T-Mobile a couple days early. The phone is scheduled to officially launch in the United States on Wednesday for $199 with a two year contract. People not dismayed about Microsoft confirming that there will not be an Windows Phone 7 Series upgrade have already posted unboxing videos on YouTube detailing the phone in all its goodness.

Update: More videos! Check them out after break.

Let’s face it, the Nexus One is a beautiful phone we would all like to use. The phone is already out for AT&T and T-Mobile networks and coming soon to Verizon, but it has no word for Sprint. That’s about to change.  Just a little past a day after the announcement that the phone would work over AT&T’s 3G bands comes word from Sprint that they will be carrying the phone, and that a release date would be announced “soon”. Verizon still has to get their CDMA version of the Nexus One, but now we known that every major US carrier will sport the phone (probably at the same price) sometime this year.

The first pictures have emerged about the Celsius X VI II mechanical cell phone, the Papillon. The phone, which will be announced at the Baselworld watch show in Switzerland, will cost an arm and a leg ($300,000) and have the most intricate micro-mechanics of any gadget in modern history. In a a slightly old article in PCMag, co-founder Alejandro Ricart said, “We want to take the useful functions of the cell phone and try to re-think them, and re-create them in a mechanical way.”

For those that are rich enough to pay for it, they’ll notice that the body is mostly transparent, so the owner can see the mechanical guts of the phone they paid so much for. More will be unveiled next week, but until then the phone is still shrouded is mystery, even with pictures.

It’s one thing to be a Lego addict, but quite another to make a work of art. Lego artist Nathan Sawaya achieved the impossible: make a Blackberry fun to use by making a life size version of the Tour 9600. His Lego version of the BlackBerry Tour, with a whole televison stuck inside, will be used  for the BlackBerry developer conference this year. One thing is for sure, it’s a fun reminder of what the Nexus One had during its launch back back in January.

Those with Windows Mobile 6.x wishing they jumped on the mobile bandwagon later when Windows Phone 7 Series comes out, all is not lost. Someone going by the name of LeSScro made a theme for existing phones, and for a theme, it looks impressive to say the least. This user interface skin includes Xbox Live (supposedly), and can make old phones look young again. Video to ease your jealousy over an unreleased mobile OS after the page break.
