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.
To get started, head over to the original thread.

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.
