OK folks, after 0.9.5 update (Cydia installation) turning everything off in boss prefs and reboot using boss prefs USA tMobile works!!! After reboot you can turn on edge and wifi, works fine! Great job Dev Team, thanks one more time !!!

Again great work Dev-team...With 0.9.5, much better! I can switch sim cards (swisscom, orange, telenor, fido) and its automatically searching and recognizing networks! After restart also, no need for airplane mode off-on. Just that issue with USA tMobile, dropping outgoing calls. signal disappears but comes back in few seconds, incoming fine, text fine, edge and everything else is fine...GREAT JOB GUYS AND MANY THANKS! Keep up the good work!

yes my friend, same thing....hopefully dev-team will fix that soon...good luck!

First of all , I want to say thanks to Dev-Team, Great work guys!!! We all waited this for long time and i hope it will be updated soon. I have tried with few different sim cards and its working with Swisscom, Orange, Telenor without any problems. Main thing is the installing "yellowsn0w" from installer and disabling everything from Boss Prefs. tMobile USA still has a problem like many others I have the same problem. After placing a call signal is gone and to get it back need to do the terminal typing...and its back again...Text messaging works fine and EDGE also. So i hope there will be solution for this soon. Thank you one more time for all the users around the world!
