My Phone Is Dying

I think my Sony Ericsson T630 is dying. This past week while talking to people on my phone I was hearing crackling sounds. Yesterday while talking to Nibaq he told me he was also hearing the crackling sounds on his side. So yesterday night I went into the “Service Tests” menu (From main screen press > * < < * < *) and I did the mic test and as I had expected all I was hearing was the crackling sound. Seems the mic on the phone is fucked. Now I don't know what to do. I am soo bored of all the phones in the market. I don't like Nokia, I hate the samsung brand, siemens are interesting but the phones they have which I like don't have bluetooth. Motorolla also have interesting phones but even the ones with bluetooth don't work with my mac and pda the way they should. So that leaves Sony Ericsson. My past 4 or 5 phones were all Sony Ericssons. They work best with my Mac (isync) which is the most important thing I look for in a phone. But there is no SE phone that interests me now. The S700 is cool but big and expensive. The P series I dislike because of their Symbian Os. That leaves me with the K700, which is probably what I will go with. I think I should be able to find it for a decent price now. If it turns out to be more then what I want to pay I will definitely find a second hand like new condition one for a lot cheaper. I am so bored with phones...
