No, it's the same... Just the internals are different.

Been Reading up on o2 and if you spend over £40 a month they reduce the upgrade time! Ranging from 1 month earlier to a whopping 6 months earlier. To get it 6 months before your contract is due an upgrade, you need to have spent £80+ a month. Still good tho!

I'm tempted by it, but my MINT 3G is only 4 months into it's 18 month contract.... Damn! Could always sell it and buy a PAYG 3GS I suppose....
