Orange France is admitting that they are capping iPhone 3G speeds to 384kbps; this as a recent survey has showed significant regional differences in speed.
Orange will be bumping the cap to 1Mbps on September 15, however that cap is still under HSDPA's theoretical maximum and less than what European T-Mobile users have been experiencing (up to 1.8 Mbps).
