Will Unlocking my ROGERS LG XENON phone let me use custom ringtones

I am with rogers who has branded my phone to make me download all ringtones off rogers sites, not letting me use my own (the phone has this capability but its blocked, I can use custome mp3s that are >300k this is blocked)

Please Read:
No I dont want or care about your free ringtone site - I want the actual question answered
No I dont want or care about your cable trick, I want the actual question answered
Yes I know my mp3s need to be under 300mb - I have done that I want the actual question answered
No I dont want to fuck around with bluetooth and sending shit back and forth to set up ringtones, I just want to know if unlocking my rogers phone will let me set my own ringtones

Thank you to anyone who will properly answer this question
