how to get H signal on three uk? bold 9900

[joelk2]

hello all,

ive got an unlocked o2 bold 9900 and im using it on the three network but can only get 3g signal.

i know three support H as i was getting it on my samsung gs2.

the bold still has the o2 branding, will this make a difference?

O2 bought stock for the 9900 models that have firmware disabling the H/H+ networks, but the phone has the hardware capable of using H/H+, from what I've read.
