OK, no compression options or anything?

By the way, if anyone finds themself in Tanzania and in need of a
prepaid cell data line, I found the ultimate:

http://www.vodacom.co.tz/docs/docredir.asp?docid=3530

Good speed too.  Tigo is almost as cheap but incredibly slow.
Zain/Celtel is as fast, but at nearly 5 times the price of the 250MB
Vodacom bundle.  The only option I didn't try was Zanzibar Telecom.
