Was just looking through oranges terms and conditions and it looks like they will charge me for using wi-fi as well? How is this possible. its not their internet im using :S
They won't charge you for using open, unsecured wi-fi.
There are systems in place that allow you to use secured wifi hotspots (such as BT openzone, although I can't recall specifically if they are on the list) and be billed to your mobile account. That is what the terms and conditions refer to.

with o2 i get 1mb free a month and then they charge me £3 a meg afterwards
about to renew my contract so gonna have the unlimited 3g bolt on added
MW
how much does that bolt on cost?
people keep menchencing retention deals but i dont quite get it and google came up wid nothing.
Basically if you wait until your contract is about to expire and tell your provider that you have seen an amazing offer through another provider (do some research) they will usually beat that offer
So basicaly i just say i have got a real good offer on o2. and then they will just start offerign things. Sounds good 
How many MB would streeming a film be off the internet onto a phone? Coz i was thinking how cool it would be to be able to do that but i dunno if id get more then 1 film a month in to a 500MB orange thing.
