iPhone upgrade.

[BoomAM]

Hi.
Despite only being 9 months into my 18 month contract, CPW are offering me an upgrade.
Which, i asume, is to sign another 18 month contract with them for a new phone.
Lets say i was to hypothetically take them up on it and get myself a nice shiney new 3GS to replace my 3G, would they then, again, offer me an upgrade in 9 months time again, in theory allowing me to upgrade to the iPhone '4' as it were?

Thoughts & advice?

Thanks in advance all. .

I very much doubt it, surely that's not a sustainable business model?

Also, the iPhone is now going to be available on Orange and Vodafone (confirmed) - it's highly likely that the deals will get better so I'd sit tight for now regardless.
