Someone I know has just bought a wifi/3G iPad 2 in the USA for use in the UK but has found she can't use the 3G outside the States. Her iPad is 'hard-wired' into Verizon and has no SIM-card slot, like European iPads. Is there any way she can get it to work with any of the various UK service providers or is it a case of buyer beware? Advice or similar experiences would be welcome.
