I've recently discovered that my phone no longer looses it's t-zones connection preference during a reset. I've been suffering like everyone else, that every time the phone resets it reverts it's network selection away from my t-zones to the other t-mo plans. Like everyone else, I had to goto Pref/network to reset it to t-zones.

Since I started using my Sim Max 12 in 1 sim card it no longer resets during the reboot. I guess it's something in the t-mobile chips that forces this.

Just to clarify, I travel alot and use local chips in different countries. It's just more convenient for me not to carry around and track 5 phone chips.
