I was having a problem with IPhoneBrowser not recoginizing my iphone as jailbroken even though it was broken using ZiPhone 2.5. Since I had already installed a bunch of stuff I could not use Tackett's very useful post in it's entirety
http://www.modmyi.com/forums/showthread.php?t=47531 But I was able to extract out the steps that worked for this problem.
These are the steps I used from Tackett's post:
7. Open Installer
8. go to "sources" in the bottom right.
9. Push "edit" on the top right.
10. Push "add" on the top left.
11. type in i.unlock.no (leave the
http://) and let it refresh
12. Go to install
26. scroll down to "unlocking tools" and tap it.
27. scroll clear to the bottom of the list and tap on "Ziphone ibrickr fix" and install.
29. Reboot the phone. REBOOT IT. turn it off and then back on.
Now IphoneBrowser seems to recognize the phone as Jail Broken.
