Flash SG3 to vm or boost?

[Bmoreandroid]

How yall feel about flashing SG3 or using GNexus to boost/ virgin since they now have 4G (wimax)? It will throttle after 2.4gb.

Will i have to root to get the latest OS?

Do u think (wimax) on prepaid data speeds will be enough to handle a sg3 or gnexus?

Thanks in adavance
