Dont quite understand what you mean by that . . . im more concearned with how quickly i will use up that allowance not weather or not i will actually get 1 GB...

anyway i fully intend to carry a spare battery since theyre super-cheap to get hold of, but yeah i had to lean the careful balance of brightness and email checking intervals for my pre, and ive read all the comments on the n900 battery so i know what im getting into.

Thanks for the advice
