Switching to mobile theme does not work

I tried using the 6.x beta version of this module and there's an issue in the hook_boot() that will prevent this module from doing what it's supposed to do - that is, to switch to a mobile theme on a mobile device. I looked at the 7.x version and this issue looks partially fixed.

I'm seeing two issues:
1) When a mobile device is detected, we're setting "theme_default" to "mobile_switch_theme_default". This is incorrect. It should be set to "mobile_switch_theme_mobile". Looks like this is fixed in 7.x.

2) Browscap returns a string for 'ismobiledevice', not a boolean. The check for "(bool) $get['browser']['ismobiledevice'] === TRUE" will be TRUE even if $get['browser']['ismobiledevice'] is equal to 'false' as a string, because then you run it through the bool function. ((bool) "false") will equal TRUE. In general, there seems to be an overuse of the bool() function. I've decided to fix this by keeping the 'ismobiledevice' value as a string -- so when you check for the emulator, I've set that value to 'false' or 'true' as a string also. The way it was written, 'ismobiledevice' would have been 0 or 1 if working with an emulator, and 'false' or 'true' if working with an actual mobile device.

Patch will be attached.
