well...i did #9 because i needed the stock rom to flash 4.22. rebooted fine but was wondering why i had 2 bars in a t-mobile dead zone.
updated to 4.22 then went to "about phone/status" and my network is listed as AT&T.
in "access points" it lists T-Mobile with everything listed like before [ i'm on the t-mobile $30 plan]
in the "testing" [*#*#4636#*#*] current network: AT&T.
i'm assuming the stock rom caused this?
how urgent is it to get this back to all t-mobile?
edit: apparantly i now have roaming it switches to AT&T when there i no tmobile signal [i'm on pre-paid]
