I have a serious problem. I downgraded my imported (unlocked) 3G to 2.2.1 after trying 3.0 beta. I am glad I am back to 2.2.1 in terms of stability but with the new baseband my iPhone looses 3G / GPRS network connectivity from time to time until I put it in Airplane mode and back. This really sucks.
Anyone else noticing network loss? I can place calls, I can actually use 3G data until it drops the connection. It won't turn it on by itself after loosing it.
Any workaround? Any help is greatly appreciated.
