I'm moving in to a flat soon ( yay me ) and don't want to be tied down to a landline and broadband contract. (Incase something bad happens and I can't keep the flat) I'm thinking of getting a 3GS to replace my dummy phone (My ipad 2 is for my power apps anyway) and use a sim card from 3 with the one plan. For those who don't know the one plan allows unlimited 3g data with thethering. ( Feeling jelous yanks? ) My question to those who know. Does the one plan allow tethering through USB or will I need to jailbreak for wifi hotspot functionality? And how are 3G speeds from three? Thanks!
