Apple has been forced to withdraw claims in its marketing that the new iPad has "4G capability", following intervention from the Advertising Standards Authority (ASA).
The regulator said the manufacturer could not advertise its tablet computer in this way, since there are no 4G services compatible with the device in the UK.
According to the Guardian, more than 40 complaints were received about the way the new iPad has been advertised.
Mobile broadband providers are being forced to wait to launch next-generation services in Britain, with Ofcom currently consulting on Everything Everywhere's plans to utilise spare 1,800MHz spectrum.
Other broadband providers are waiting for Ofcom to auction off space in the 800MHz and 2.6GHz spectrum bands before launching 4G services.
But even when 4G services launch in the UK, the iPads will not be able to access super-fast mobile broadband as they will be incompatible with frequencies used.
The UK joins Australia in banning the use of the "4G capability" label with the new iPad, which was released in March 2012.
