Droid RAZR MAXX HD
I received an automatic upgrade from Verizon that converted my Ice Cream Sandwhich operating system(4.1) to Jelly Bean (4.1). I did not want that upgrade because I prevents me from my need to sometimes use the FoxFi/PdaNet (WiFi) app to access the internet with my laptop by WiFi.
Q1 Is it possible to reverse the upgrade?
Q2 Assuming the PdaNet still can enable Bluetooth and USB access to the internet thru the phone, does anyone know the relative speed of those two options? (The WiFi option was 5100 kbps.)
