well, since this thread is not officially closed i might want to add some things to the buyer.

1. O2 repair cost is NEVER cheap. Even to change my XDA II casing it cost me S$ 160 (yes, i asked in singapore).

2. Even if you tested it for 1 hour (instead of 2 hours as the seller claimed), you should have a very good picture about soon-to-be-your phone. I tried to re-read and understand the thread where DFlo made his offer and he said "Some dust inside I'd say" which shows his uncertainties.

3. The buyer have mentioned that it works 99% of the time and the problem occur only 1% of the time. I think during that 1 hour you should've pressed the troubled button for quite a numerous time and if you find that the figure 1% is exaggerated you should've settled it on the spot with the seller.

4. When he mentioned about personal warranty, you should've asked what things would this warranty covers. After all, it's not a manufacturer warranty came with a disclaimer and other legal notice. In another words, if you didn't ask anything about the coverage of the personal warranty, it's like giving him the privilege to set the warranty coverage whenever he wants it. And he's not lying to you since no matter how small the coverage is, it's still a personal warranty (you didn't ask right? fair enough?)

So in this case i'd say that i'm backing DFlo as the seller. For the buyer, i have nothing against you. It's just my opinion. And better be careful next time
