I have had the new Samsung Galaxy S 4G for nearly two months now and EVERY WEEK it has network / connection problems, can't make or receive calls. I have to reboot every time to get it working again. Signal should not be an issue since my wife always has good coverage with her Nokia N900 phone. They have given me two new sim cards and that did not fix the problem. Anyone have suggestions or similar issues? Absolutely love the phone and how it works, but I am ready to toss the damn thing since I never know if it's working so I can receive calls... any help would be greatly appreciated!
