I'm getting my iPhone on Tuesday What I want to know is.... I can use my home wifi when I'm at home, I also am signed up with The Cloud, but there's not many places that have that, and o2 wireless (my network) isn't really available in many places yet (although apparently they'll have a large network by 2013).
I notice BT Openzone has a large network, I'll be able to wifi pretty much anywhere, but costs £5 a month.
So what do others do about wifi when out and about?
I use 3G most of the time when out and about or look for cafes with free wifi. Mcdonalds is usually the most reliable! I use it or browsing Internet, reading news and checking emails and I haven't been anywhere near my data limit. BT Openzone has good coverage but I wouldn't use it enough to pay for it.
most contracts will now give you 500 but if you go over that - as i do, then you still can use the internet on 3g but it is so much slower and emails dont seem to download if no wifi - which is very annoying
