Sony's Netfront vs Apple's Safari Questions

[gino_76ph]

i have had my 2nd gen ipod touch for a while now and whenever i go to a "free" wi-fi hotspot (say a shopping centre or a fastfood chain) i can't go to the internet. i do not know why. i think you need to "register" first with the existing network on the place but sometimes there are dead bits on the site i.e. the site loads incompletely.

how is Sony's Opera browser on the new X-series walkman? does it accept Flash? does it "scans" for free and paid wi-fi signal on a given area? or can you manually find it?
