It is thought that the update will be rolled out by T-Mobile pretty soon, however if you cannot wait you can grab the ROM for yourself here. As with any leaked ROM we cannot say if it is official, therefore it is up to you whether you trust the uploader. We recommend being patient and waiting for the official rollout.
According to IntoMobile the update procedure is pretty simple, however if you have a rooted device going back to stock software is not as simple. We would strongly recommend backing up all personal data beforehand just in case.
Each Gingerbread ROM differs depending on the device you are running, the official Gingerbread notes suggest that it should bring an improved UI, an easier to use keyboard and better copy and paste functionality. In the background there are probably lots of bug fixes and security improvements.
If you were brave enough to update your T-Mobile G2 with this ROM we would love to get some feedback from you, therefore feel free to answer any of the following questions: Did the update process go smoothly for you? Were there lots of noticeable changes and improvements upon installation? Would you recommend this particular update to others? Let us know in the comments section below.
