i have purchased a blackberry 9500 storm which was on vodafone but now unlocked and now using o2 but the phone will not connect to the internet when ive topped up i thought i would be able to change the connection settings by putting in o2payandgo but it wont allow me to do this it just has o2uk 3g or 2g i have gone onto advanced options and onto browser and it says default browser config and it has a blank blue box is there any way of getting it connected without spending a fortune on calls and getting nowhere?
