I used the Support Tool to restore and update, after update I believe it did something wrong as my radios had stopped working. Took it to Verizon and he put a new SIM card in, and after a Factory Reset, I had 4G and 1x, but no 3G anymore. I thought it still wasn't working correctly so the rep got me a replacement. I just turned on the replacement and I still don't have 3G. So my question is, did the update take away the option to switch to 3G? If not, do I just need a new SIM card? Also, the "new" phone was already setup (i.e. initial setup had already been completed), so if I do a factory reset will it reset the SIM? Need help.
