1.I'm on the 02 30 tariff for iPhone and noticed that im being charged 20p per min for internet over gsm so even though my data is unlimited wen it drops 3G im being charged extra? or have i read this wrong? 2.Having just bought the iPhone 4 what accessories do i need for nike + ipod? (just the shoe sensor?) 3.It says i am allowed to change tariff after 9months so would i be allowed to change to the simplicity for iphone after 9 months or not?
