Hi. I have had an unlocked iPhone 4 for a while now on pay as you go. When I changed from 3GS to 4, I kept my O2 SIM which still contained half a year of free unlimited web. Well, January '11 and this all comes to an end. I basically want to know what the cheapest and best (coverage, cust support etc.) carrier/price plans on pay as you go are in the UK. I am probably OK with a 200MB cap as I don't use the mobile internet as much as now I have Wi-Fi (I used to always be going over my 500MB cap whoops.) I generally text a lot more than I call as well. So yeah Thanks in advance for any help!
