I'm thru with version E... its a mess. Tethering is all messed up. Even 4G internet is gone screwy... at least half the time I need to reload a page because it times out, then loads normally. Speeds seem just a little slower.. not much, could be a fluke... but anywhere I go since the upgrade... and its chugging on first attempt on almost all internet functions. SpeedTest is giving me 4500down/2800up... slower than my usual 6200down/4500up. I'm wondering if the PRL got messed with too? If anyone could kindly point me in the direction to a downgrade... many thanks in advance.
