We have known for a while that DJ_Steve has been working on an Ice Cream Sandwich ROM for the Dell Streak 7, and now, it's finally available. Thanks to him and Giveen, you are now able to take part in indulging on Google's latest dessert.
All you've got to do to get the latest version of this ROM on your tablet is download the file linked below and, providing that you have NVFlash drivers installed and your device is in NVFLASH mode, unzip it and install it onto the device.
Note: This is still a beta release, so if you try to install this and something goes wrong, keep in mind that you agreed to install beta software. If you do get it working, tell us how it went!
