Re browsing, I think that the so-called 3.5G, or more accurately HSDPA is 'throttled' or simply not available in most areas. The reason I say this is that my phone will sometimes display a 'H' instead of the usual '3G', and during that time it is blazing fast. I've only had this once in the Saujana Utama area.
Frankly I'd just be happy to get rid of Operan Mini and get back to the BB browser.
Sick of non-BB phones
