Wow that's ridiculous. Here in the UK it's a consumer right to return an unwanted item within 14-28 days of purchase. Any such clause in the T&C here would be null and void the second it was printed as it seeks to supercede statutory rights
Ah well, try what I said earlier about maybe them waiving the restocking fee in return that you'll buy your i5 from them. If they refuse, buy elsewhere.
I mean, really all you lose is 10 minutes talking to a person.
