[Q] OTG possible without the live dock ???

---

hi everyone, i was about to buy XPeria Neo, but while surfing the net, i got to know that with 2.3.4 update, one can get USB-OTG feature via live dock..

Now the question is that CAN we USE the OTG feature with the normal host cable and without any external power supply ??
the users who are on 2.3.4 pls test and reply..
the otg(host) cable costs only $3~$5.

if someone had 2 micro usb cables, could try this: http://www.youtube.com/watch?v=COkLEJGo6vo

i only have 1 so i'm going to try that

thats a clumsy option man,
one can get an OTG cable than destroying one cable and a female-port

Would be good to know if this is possible, if not looks like buying a live dock might be the way to go.

Live dock can take an external power and supply power to connected devices..

Yep, I know but would be nice to see if this can be done without the live dock somehow. :)
