Motorola i760

Hello forum-goers... I recently upgraded my i530 phone to an i730. Very disappointed. My i530 was great, and this i730 drops calls all the time and has very poor signal strength. My i530 always had full signal in my area, so it's not the fault of the network. I love the i730 phone, but it's too bad the radio sucks in it. Anyway, I am wanting to know if the i760 is an improvement from the i730. I personally like the look and design of the i730 better, but I'd rather have a phone that WORKS. Has anyone used both phones, and if so, could you tell me if the signal strength is improved with the i760? Thank you very much.
