My new iPhone 4S cannot connect to GSM network in Slovakia
I have a brand new iPhone 4S bought in Apple Store in Czech republic. Phone is always searching for GSM signal. After full phone restart it finds a signal for about 5 minutes, and then drops it. I live in Slovakia and use TMobile GSM network. I also have an iPhone 4 and with the same SIM card I have never had a similar problem. Someone told me to try turn off 3G, but from iOS 5 it not possible. So now I have my most expensive iPod yet. I'm very dissapointed.
iPhone 4S, iOS 5.0.1
