In answer to questions about the $20 plan:
Many of you have asked about the shared data plan listed on the Apple website. This reference was an error and is being removed.
Fair enough. This puts us roughly at par with AT&T in the US (where the ‘unlimited’ data plan has the usual nGB ‘fair use’ cap). In other words, while the $20/mo idea would have sucked ass, and a $20 one-off would have been fantastic, we’ve actually wound up with exactly what we would have expected: two tiers, pay-as-you-go, small or large, monthly.
Now we just have to convince them to add a $5 250MB 24hour plan, like O2 and Orange have made available ;o)
