Yellow H on W760?

Hi,

Just bought a W760 today and its working fine. First Sony Ericsson phone so I am still getting used to its symbols.

One that is concerning me is a yellow H that appears next to the signal strength in the top left of the display, where the key for locked keypad also appears. I have read and reread my manual and can see no reference.

I am thinking it is bluetooth? I am only guessing as it has appeared around three times today, for often 10 minutes or longer?

Any guidance is much appreciated?

Don't worry that yellow H is just your HSDPA which is part of your 3G service and allows high speed downloading.

Okay, so its part of my 3g, thanks. Does it do anything, as it just randomly appears?

I wasn't aware I was using 3G, is there any way to turn this thing on or off?

Go to setting->connectivity->mobile networks->GSM/3G networks

Many thanks, I have changed it to just GSM now. :)
