The unofficial Gingerbread update for the EVO 4G is available for download, and according to people who have already tried it out, it works seamlessly. That is great news considering that last time when we saw Android 2.3 running on the EVO 4G it was plagued by imperfections. Unfortunately, the Sense UI version appears to be the same old one like always, but we cross our fingers that HTC will treat us to an update in the official release. So, if you are ready to try the custom ROM out, check out the link that we have provided below and please, do not forget to backup. Or, if such tinkering is not something that you are fond of, you can always hope for the official update to start rolling out in the forthcoming months.
