Had the local 12 year old neighbour Get me root access on my much loved Samsung S2 and he has tweaked and twisted it and it is running fantastically now.  All the old problems of dying battery and funny SD card failures have stopped with him putting Jelly Bean on.  I was trolling through the settings and see a setting listed under "Radio"  with nothing input yet in the settings.    The title at the top says  HSPA.  Can anyone tell me if I should choose UMTS ONLY,   HSDPA only,  or   HSDPA + HSUPA in the settings?
Again  on Vodafone with a Samsung Galaxy S2 with Android 4.2.2?   Thanks in advance.

P.S.  this guy is a genius.  12 years old and with a Simple Android phone which he brought for just over a hundred bucks.  Mother confirms he has had so many different Roms on his phone and always managing to get his phone going again when he strikes trouble.   A  creative little dude who is learning heaps.
