Ok.... I had some issues with losing 4g and it bouncing in and out about a month ago. I tried updating because I read on this forum there was an update coming out that fixed it. When I checked for updates it has said for a month "system updates not available now. Check back later." Then I lost 4g completely and it has never returned. Now my 3g has been losing data connection and bouncing in and out juat like the 4g did. This has been going on for about 3 weeks. I have never updated but it still says system update not available now. Sooooo frustrated?? What gives?!? Any ideas?
