I have an iPhone 3GS that recently ran out of contract from O2 and as such I have switched to 3 network on the 100 Sim only deal. The thing is though I used to have 500mb usage allowance on O2 and id never ever go near it (maybe 200-300mb) a month but now I'm on 3 I get 1gb which SHOULD be plenty! However I have seven days left to go before my next allowance and I only have 150mb left! I really can not understand how my usage has increasd so much! I'm essentially quadrupling my data usage which I just don't understand how it is possible. I mean I get 3G at work now so maybe get a bit more usage out of it a day but I really can't see why this is making such a huge difference! Is there any other reason my usage could increase so bad?
