I used ziphone's instructions and here's what I did:
Upgrade from 1.1.2 OOB to 1.1.3 w/itunes using shift+restore
Ran ziphone - do it all - unlock/jailbreak/activate

Great, phone is up, synched contacts, went on my merry way EXCEPT:
There is no installer on it
There is no EDGE access - just a little E

I have a Tmobile Blackberry unlimited plan.
I went into EDGE settings and set it to wap.voicestream.com, internet2.voicestream.com, & internet3.voicestream.com, one at a time, with a poweroff between each attempt. No luck.

So, I don't know how to install installer & I really need EDGE to work. Advice, please?
