I can't really see how comments like get a shitePhone help... ive been accessing forums on the internet for a decade before the shitePhone came along with no issue so this isnt the problem.
If Opera Mini 5 won't work with the crappy LG however, try 4.2 - if it still does not work, take the phone back. I think Mel's is LG and though I only tried downloading via the Opera /m site, it would not let me download and install Opera Mini when I tried, came up with some silly error. I must try again sometime!
As for the phone being 2g - that does not matter, because unlike the crappy iPhone and its even crappier Safari, Opera Mini does not require a 3g connection, due to its all singing and all dancing caching system. After years of running scared, Apple finally allowed Opera Mini to be released on the iPhone, maybe you iPhone users would like to download a real
mobile web browser and experience. Oh yeah, my Windows Phone does flash, how's your iPhone getting on? Oh wait now, you don't know what flash is?
