For everyone who has had LTE problems read this about 40% of LTE online in cities: http://s4gru.com/index.php?/blog/1/entry-311-editorial-cmon-people-you-really-do-want-access-to-the-...
Good article, but old.
However, I still agree 100%. Early adotption usually leads to issues. If your not prepared for the issues then you shouldn't have adopted early.
i install the SignalCheck Pro app on my LTEVO, and the difference on signal, even standing in front of the antenna is -30bd in LTE. example, the 1xRTT or the EV-DO is in -65db and the LTE is in -95db. so, the problems is NOT software, is Hardware. the very poor LTE antenna is the issue, not the Radio File or the updates.
