i have the 7100g with cellular one too, i use cellular1wap for the tcp code, i have ramble im and hello world with it, only thing is you cant use your browser when tcp is set up , you have to go to the tcp settings in the options menu and delete the cellular1wap from the tcp so it is blank. then you remove the battery and let the bb power back up and you can use your browser again, its kind of a pain but its not too hard, cellular one is coming out with the 8700c in march or april, and as for the ringtones i have like 30 of them on mine so if you have trouble pm me!
