I'll keep this short: The iPhone 4S has never let me down so far. Paying attention to the battery, it also comes from having several days, especially if you limit the mobile data (EDGE) or completely shut off, at least temporarily. Only the reception could be better, have from time to time under the impression that the position of the hand still has an influence on the reception. Received other smartphones 3G are mine only Edge displays. All in all, however, very satisfactory, although the price is a bit high.
