Hi guys .. Hope this helps someone out there.. I was having problems with T-Mobile T-Zones .. Only thing working was gmail emails.. I am getting 502 error message in safari.. I was so frustrated I did Restore 1.1.4 following Ziphone instructions I performed the UnLock..which is the Easiest

Before you do that...do you have Community Sources Installed? It turns out I forgot to install Community Sources.. see if you have it installed? Once I installed it my FULL T-Zones was back
After my Restore to 1.1.4 & UnLock I did the following (Perform in order):
*Select Installer.app > Select Install > All Packages > Community Sources > Install
*Select Installer.app > Select System > BSD Subsystem > Install
*Select Installer.app > Select Install > All Packages > OpenSSH > Install
T-Zones $5.99 Proxy Hack (If you currently have these, UnInstall & ReInstall Them):
Select Installer.app > Select Install > All Packages > Bigboss's Beta/Experimental Source > Install
Select Install > Tweaks (1.1.3) > Install T-Mobile 1.1.3 TZones Hack..
Settings > General >Network > Edge > APN: type in: wap.voicestream.com Leave Username & PassWord Blank
Restart phone and your done!
Hope This Helps ..
