the particular place say in a lobby is generally known as a wifi hotspot. you would turn on wifi, it should automatically scan for access points/hot spots SSID. it may even connect to one, but you can choose which AP you want to connect to based on where you are and teh SSID. the SSID should be configured so you know like for example JoesRestuarant.
next most public wifi will have a login in splash screen once connected, usally you have to get a free card with a username and password from the counter wherever you are. some may even charge you a fee for x amount of time. well thats how they do it here.
i think i miss-understood you... you want to know the best way, not how to lol
just using the standard proceedure i described will be fine if you have your own personal security but i dont know what security ipads have. i wouldnt worry about connecting to a proxy or vpn unless you want to be naughty
, just dont do any net banking or use online purchases if your really concerned. what i do is just normal browsing on public wifi hotspots tho and never caught a virus or being hacked.Edited by stubass - 12/31/11 at 4:11pm
