is there a way to instal .jad files without a data plan? i've done it before but it was because i downloaded the .jad file and within it it had all the .ota file does anybody know if you can download the .cod? or should i just look for the .alx files and search for it on the web? also is there a way to tether a bb to a computer and use the computer's internet isntead of the phones? i know that you can tether it and use the phones data plan but is there the other way around?
