I have a BB storm 9530 that is currently unlocked. It is a verizon wireless phone, but I am currently using it on the t mobile network. I had upgraded the phone's os system to the official 188.8.131.528 os that was released by verizon online .. the phone was much faster and responsive, but I could not make any phone calls. I was recieving the "no circuit/no channel" error code.
Can you please instruct me on what to do. I would like to find an os that will work on the T mobile network. I am sick and tired of using os v184.108.40.206 (platform 220.127.116.11)
Thanks in advance
