hello. I have a big problem with my samsung galaxy i7500. I bought it last year (croatia) and since day one nothing but problems. first of all NPS won't recognize my phone so the program is useless.I can't upgrade it either because it needs to be in sinc with NPS.battery life is morbidly short.bluetooth won't work..... I'm a total noob,so please tell he how to fix all those bugs by upgrading or something. I'm so frustrated,phone was expensive and yet it's like the model of a 3g phone. thanks.
