Here lately, I've been trying to upgrade the custom rom on my HTC Titan thats been unlocked for use with T-Mobile. However, when I decided to upgrade, I realized all of the newer roms are of course using the newest radio (v17) which absolutely refuses to see my T-mobile sim card. My girlfriend has AT&T and the second I throw her sim card into the phone (with the version 17 radio) it accepts the network and everything works as usual so I know its got to be the sim card. All of the custom wp7.8 roms with the version 16 radio have broken links and are out dated so I'm hoping to find a fix for this. Or at least find someone else who knows of the issue. Hopefully someone on here can find some kind of a solution.
