Below is a statement from the Epic Product Manager regarding the leaked release (DK28):
Sprint is working on a software package for the Samsung Epic4G that will upgrade it to the Froyo version of Android. Over the weekend, some users were able to access and download a test build (DK28) for the Samsung Epic from some 3rd party developer sites. Unfortunately, this is not approved software for Sprint production devices and we strongly recommend that users refrain from loading it.
Software version DI18 is the current production version of software. When new versions of software are available, users will receive a notification from Google on their device stating that an upgrade is available for download and installation. While we are unable to communicate a firm delivery date, rest assured that we are working on a software upgrade to Froyo and hope to have it out in the very near future.
Are you serious? We will get the 2.2 update on the "flagship" of the Samsung Android devices 2 week after google releases 2.3 on its new Nexus? Why is this taking so long while India and the UK already have it?
The reason we get it so late is because they have to make sure the Sprint apps, most people don't use, work with the new release instead of making them an optional install after they push the update out and then make sure the Sprint apps work. Wake up Sprint make the Sprint apps an install you can go to the market for instead of pushing them on us and making them un-installable. I hate to say it but almost sounds like you are pulling an Steve Jobs...
I'm sick of waiting... thats why I installed it. Get a move on Sprint. That, or let some of us users beta test the software, so it can get pushed out faster.
near future isnt a good enough answer for me...
