I just received my Motorola Xoom back from having the upgrade to 4G LTE. Unfortunately, I can't get service that well. It fades in and out for several moments leaving me hopeless to browse the net. I had better reception with 3G it seems. I am reading a lot of outages. Is it more than just me getting poor service? I thought 4G was faster but I haven't gotten that side of things yet. Hopefully the get this resolved soon. I miss my Xoom!
