I was very happy with my 3GS phone: Right, Efficiency; speed ... But I very quickly déchantée. The phone was defective, among others: it off automatically after about 4 minutes converstion ... it was a gift for my father. this one didn 'spoke that after 15 days I tried to contact the seller. SMART DEALS didn 'never responded. I tried to arrange with amazon, AZ The guarantee was refused on the pretext that I had not contacted the seller within 15 days; I contacted Apple who answered me that they can do anything: jailbreké phone and bought in 2009 !!! Smart deals had yet guaranteed me that the phone was new. In other words, if you bought at smart deals, know that, nor any service, no guarantees. contrary to what is written. I lost 300 euros. but what makes me the most "evil" is that it was a gift.
