So i decided to do some speed tests while tethering my e71-2 to my macbook. All tests were done with the phone in the same location connected to 3.5g/HSDPA on Firefox in OSX 10.5.5 I'm in san antonio on At&t using the wap.cingular APN because i "don't" have a tethering plan.
Unsuprisingly USB came out to be fastest, Bluetooth couldn't pass 700kb/s and joikuspot revealed mixed results :/
