@stanwood Thank you for the update. I went back and did some more research and needless to say, I'm less than impressed with the knowledge of the ATT people I spoke to at the store. You're right that 4G isn't going away and the way they built 4G, its basically the backbone for 5G technology so not sure if the ATT people were just fear mongering, or just didn't want to deal with an OS that was clearly very unfamiliar to them.
Its good to know UT is continuing to work on this problem. I really liked the OS. The simplicity of it, the lack of apps and ability customize it. Not to mention, its very snappy, even on older, under powered phones like the N100.
I know my post sounded negative, but I'm not giving up yet, I see a lot of potential for this OS and will continue to work it. Thanks again for the update.
