[Braillenote] Cell phones

[Hejcoop]

My son has a briallenote 32, soon to be replaced with an mPower.  We  are 
getting him a cell phone and we are wondering if it is useful tog et one  that 
interfaces with the braillenote.  Can anyone tell me the advantages to  this 
and 
how it might benefit him?  Also what phones are people  using.  Thanks
