It looks like Vodafone are getting closer to deploying their 3G over 900MHz spectrum:

The question is, will our existing hardware work on this? I.E. as the current 3G cellphones / Vodems etc assume 3G is on 2100MHz, will they discover 3G on the other bands too? Or will we be in for hardware or firmware upgrades again?
