Successfully installed MJ on our site: ccmonline.org, but can't get it configured correctly.
Using:
Joomla 1.5.22
MJ 0.9.11
Provider = Bluehost.com
Package = Platinum Pack
Apache = 2.2.17
PHP = 5.2.16
OS = linux
Theme = yoo_evolution
Phones tested on = android and FF UASwitcher iPhone 3.0
I've uninstalled and reinstalled
After 8 hrs of searching through the forum I give up! I followed directions for:
--Disable Mobile-Always (did that)
--Enable Component on Home Page in iPhone tab (did that)
--Enable Mobile Templates Plugin -- it's not in the installation
--Configuration wiki - too out of date to be helpful
--create subdomains
   I enabled Domain (multisite) support=yes
   Created a subdomain: /public_html/iphone.ccmonline.org
   Enabled redirect to iPhone/iPod Domain=iphone.ccmonline.org
...but still I get this error:
404 File Not Found
URL is (testing with iPhone uaswitcher):
ccmonline.org/administrator/components/com_mobilewebmanager/m

Why is it looking in /administrator... (same error through all the different attempts) and especially since I configured the redirect to my subdomain?

At first glance it appears to be a conflict between
Joomla Mobile Web Manager and Mobile Joomla.
Could you try uninstalling both and then just installing Mobile Joomla.
Apologies if you have already tried that.

Then I would install Mobile Joomla without any configuration and see if it works.

Brilliant! I didn't think I had any other mobile components installed, but in searching for Mobile Web Manager I found System - Mobile Web Page in my plugin list.  Removed it and reinstalled MJ and all is well.  Thanks so much!

Glad to hear it's working. Thanks for posting the answer.
