I dont know if anyone else has noticed, but I installed OCT 1.5 and have my speed set at 729Mhz and I have never seen Opera run so smooth and fast.
I did load Aug 28th of Energy ROM and dont know if that helps as well over the stock (it took a dump on me 2 days ago so I decided to flash a ROM)
I use to think it was a Sprint deal and it was just a slow data connection, but whatever happened Opera has never been so fast as now. I'm very happy with the internet browsing now. Feels like I have a new device.
Would increasing the speed really make that much of a difference?
