What would it equate to? roughly? For example is it the equivalent of checking facebook once a day - not that I use facebook but just want to get an idea of how limiting or otherwise 500mb per month would be. I've googled it but get such conflicting information. I have no idea when it comes to mobile phones. Also, if you set up your email account (gmail/yahoo etc) with your phone when you receive and view an email via your phone does that come off your 500mb allowance? Sorry to sound like such a div but I'm not at all phone savvy!
