The biggest advantage that GSM devices have over CDMA devices is the ability to switch from one carrier to the next, relatively painlessly and without always needing to switch your phone. Making the phone capable of that jump is commonly referred to as SIM unlocking the device, meaning you remove the carrier lock on the device which in turn allows it to accept SIM cards from any other carrier that uses the same frequencies. Technical details aside, users of the HTC Holiday, HTC Raider and HTC Vivid can now get in on the carrier swapping goodness, as they can now be SIM unlocked.
XDA Recognized Contributor cruzin_cruzing has posted a method that was originally created by XDA Senior Member sieempi for three other similar HTC handsets. The method itself routes users to sieempi‘s website, where some information needs to be entered. From there, a modified Config.dat file is emailed to the user. Users then put that on the root of their SD cards. From there, it’s booting into the bootloader, selecting the SIMLOCK option and awaiting the proper output.
At the end of it all, users should have a fully and completely unlocked phone ready for use with any carrier on compatible bands. The whole process takes only a few minutes and is rather simple. You will, however, need a SIM card from another carrier to verify that it has indeed worked.

For owners of many HTC device such as the HTC Amaze 4G, EVO 3D, MyTouch 4G Slide, Sensation, and the Vivid/Raider/Velocity, this has been a long time coming. A fully functional method to restore a device from a full brick is a pretty big deal. This then gives users more confidence when performing potentially risky tasks such as HBoot updates, ROM flashes, or turning S On.
XDA Senior Member dexter93, along with a host of other developers, has finally released this project after several months of beta testing and waiting. This is great news for many HTC users who have bricked devices under certain circumstances, and is much better news for users who unintentionally—or even intentionally—brick theirs in the future.
The method is pretty complicated and requires a number of things on the user side. The method also requires the use of a Linux-based computer and the most up to date RUU for your device. Finally, the most important thing, according to dexter93 is as folllows:
a device bricked by writing security flag 3 with an unsigned hboot, or caused by a damaged hboot via interrupted OTA update/RUU flash on a S-ON device
In other words, this will not work for all kinds of bricks. Rather it will only work for devices bricked by setting S On with an unsigned HBoot or if your HBoot was somehow damaged. While this unfortunately doesn’t help those who may have bricked their devices through other means, it will undoubtedly help many previously helpless users. It should be mentioned, though, that dexter93 and crew are looking to find way to fix other bricks as well.
For all of the information—and there’s quite a bit—as well as download links, screen shots, the full instructions, and discussion, head on over to the appropriate thread to get unbricked:

With Ice Cream Sandwich quickly spreading across Android devices like wildfire right now, new drivers for the Adreno 220 GPU found in the Qualcomm Snapdragon S3 have surfaced. These drivers can potentially lead to improved 2D UI rendering performance in ICS and, of course, increased benchmark scores.
XDA Senior Member gjcamp has produced recovery-flashable update.zip files that work across multiple devices with this hardware. Every phone running the Adreno 220 from the HTC Evo 3D to a couple variants of the Samsung Galaxy S2 may be able to benefit from these drivers, and there are currently seven different devices for which gjcamp has created threads. In his words:
…I have seen dramatically improved result on my Quadrant 3D scores with “Force 2D GPU rendering” UNCHECKED in the Setting->Develop Options Menu of this ICS Release. With this option checked I have seen improvements on both 2D and 3D. Although results are slightly degraded for 3D from post update the 2D results have doubled in value.
I can confirm this myself on my own Evo 3D that Quadrant scores were improved with these new drivers. Similarly, the 2D UI rendering does seem to be smoother, but this is always hard to measure objectively. As anyone who flashes bleeding edge tech to their phone knows, there could be side effects.
You can get started by visiting the threads in their respective sections listed below:
Even if your device isn’t explicitly, the drivers may potentially work on your device, provided that you’re running an Adreno 220 GPU and Android 4.0 Ice Cream Sandwich. However, if your phone’s not on the list, be extra careful and be sure to have a working backup to revert to.
The billion dollar question right now in the Android world is whether or not your device will receive Android 4.0 Ice Cream Sandwich. As they so humorously put it:
Few innovations have improved upon ice cream as much putting it between two cookies and making a sandwich. Which is why we all want Ice Cream Sandwich! Ok, that’s not the real reason, but we’re all excited about Android 4.0, Ice Cream Sandwich, coming to HTC.
While there is constant speculation as to which devices will be added to the ICS list, not very many firm answers are to be found. Luckily, HTC has just released a public statement as to which devices are slated to receive Google’s latest tasty treat.
Timing is the next important question. HTC has spoken up on this issue as well, stating that the updates for the Sensation and Sensation XE would begin in the coming weeks, with the Sensation 4G andSensation following thereafter. However, the schedule still remains unclear for the other devices slated to receive the OS update.
As for timing, we’re in the early stages of rolling out Android 4.0 for the HTC Sensation and HTC Sensation XE and upgrades will be more widely available in the next few weeks. The update for the HTC Sensation 4G and HTC Sensation XL will follow. Please note, once we start pushing out updates it will take time for all carriers in each country to get the update. We are working closely with our carrier partners to nail down update schedules for our other smartphones and will have more to share very soon.
While many of us are still irked at the fact that HTC’s first generation Snapdragon devices such as the original HTC Incredible and the legendary Evo 4G are not on the update list, their omission is understandable given that not even the HTC-built Google Nexus One is receiving ICS in official capacity. However, the fact that these devices will be receiving Sense 3.6 rather than Sense 4 is a bit of a bigger blow. However, you can bet that our developer community will have that covered, as they have already begun to do so.
