These cellphones sure sell out fast. After the record breaking success of the iPhone 4, now the Motorolla Droid X has struggled to meet consumer demand, with the phone now officially sold out, and the next batch available no earlier than July 23. Although the numbers are unlikely to be in the iPhone league, Verizon has struggled in the past to get the Android-based HTC Incredible into consumers’ hands as well, due to a OLED display shortage at the time.

“We have been successful at keeping up with early demand but at present inventory in some parts of the country inventory is either low or out,” acknowledges Verizon. “Since we have weekly shipments planned, customers can still order phones and can expect them to be shipped on or before July 23.”

But what about that news that the Droid X contained embedded systems that would brick the phone if it was tinkered with? Motorola responded to those concerns today:

The Droid X and a majority of Android consumer devices on the market today have a secured bootloader. In reference specifically to eFuse, the technology is not loaded with the purpose of preventing a consumer device from functioning, but rather ensuring for the user that the device only runs on updated and tested versions of software. If a device attempts to boot with unapproved software, it will go into recovery mode, and can re-boot once approved software is re-installed.

In short, the IBM-developed eFuse system will shut down a Droid X with an unapproved bootloader though it won’t actually damage the phone. Users simply need to re-install “approved software” to get the device up and running again. That’s certainly not-quite the type of openness many users would like to see, but it’s not Droid X apocalypse for hackers, either.
