Yep I am here in new Mexico and I have revived the same thing! Alas I am not alone!!! I was on sprint and was very happy, but I switched because I now work for Tmobile and I get a VERY cheep phone plan and I get the BB data plan for free..so yeah, I do have a lot of those weird busy signel dropped calls. Tmobile's offical advise is to turn your phone off and on once a day and that should help your problem. Give it a try and maybe that will help. via BB (wap.rabroad.com)~
