It is still possible only if you are using an android phone. I have been using this ROM on my Galaxy note and there is an option to uncap 3G speed under developers tools.
Here the ROM thread link--->>> [ROM][Port][4.0.3] Codename Android 1.5.5 03/23/12 Beta 4 "Ready for More?" USB WORKS - xda-developers
If I am not wrong its a build.prop mod so it can be done on any rooted android phone.
