Need better reception!

I have a Cingular plan, and my phone fell off a boat this weekend and I didn't want to go after it . It was a 6230 and it didn't seem to have the best reception anyways.

So any recomendations?.. mp3 and camera are of no real use since I have an ipod and a nice camera with me most of the time. Most of the phones seem to come with these features anyways now, so whatever comes in the best.

I just want to hear everybody I talk to, since this is my only phone.

Thanks all!!
