T-Mobile UK's "GB:MB:kB" data itemisation

I didn’t use 10 gigabytes of data on the 1st of January, did I?

Have a read of my roaming data bill from T-Mobile UK (for my G1) over the Festive period:

That must be megabytes. 10 meg’s worth of data, costing 13 quid, right?

Yeah.

This new way of laying out your data usage is really, really confusing.

Here’s what the billing system said I did on the 1st of January:

000.0010.0204.0277

And that’s formatted thus — GB : MB : kB

So gigabyte, megabyte, kilobyte.

Ergo…

000 gigabytes? Yes?

0010 megabytes. Fine.

0204 kilobytes?

And what’s the 0277 on the end?

0227 bytes?
