Hi, I was using a tariff that gave me 500mb internet use per month. After purchasing the iphone 4 I soon realised this was not going to be enough ! Im now on a tariff with 1gb of internet use. If I go over this my network wont charge me but will choke the speed. I use 02 PAYG simplicity in the Uk. I use the internet everyday ! I watch around 2-3 utube videos per day. I receive around 50 e mails per day. I look at the app store around 3 times per week. My question is what is your data use per month ? How much mb do you use per month and what do you do to reach this. I think im a heavy user.................. are u !
