Yeah the .077 is the only one from VZW but I had so many annoying issues with the speaker blast to memory leakage. I never tried sprint and bells .131 or .138 I went straight to the Telus .160. It is noticeably snappier and has better memory usage. The browser is considerably faster but i now have backlight lag which is very minor compared with .077 and you answer the phone and the speakerphone kicks on for a sec blaring in your ear. My wife has .077 and does not have any problems so i agree with the above poster each time you load one or different phones give fixes or problems.
