Maybe you love Siri. Maybe you don't. Either way, you probably want to know that, if you rock an iPhone 4S, you're probably using twice the data of someone with a humble iPhone 4.
Bloomberg reports that the voice recognition software prompts users of the newer phone to use double the data of those stuck with its predecessor.
But if you're on a limited data contract and either (a) haven't had a bill since your new phone arrived or (b) are dreadful at checking your phone bill anyway, you might want to check how much data you're using to avoid some big charges.
And if you don't care because you have an unlimited data plan, well, that might not last forever. [Bloomberg]
