Integration with Apple iPad 2 air

[Yasha Karant]

I understand that this not an Apple forum.  However, my spouse has been 
assigned an Apple iPad 2 Air from our university administration, and she 
was reluctant for political reasons to demand a Linux or Android 
"equivalent" of this unit.

I have been attempting to configure it .  I have found that Mozilla does 
not support this platform:  (quoting from Mozilla) Mozilla.org 
<http://Mozilla.org> does not have any version of Thunderbird and 
Firefox for iOS due to Apple's restrictions on the JavaScript and 
browser engines that can be used.

Are there any email apps, preferably licensed for free and not requiring 
an additional service, that will connect to arbitrary MAP servers and 
provide anything close to a Thunderbird email client end-user experience?

Are there any sys admin or equivalent level books/websites for this 
unit?  I only have found end-user documentation, most of which is 
strictly cookbook.

The unit was equipped with a Logitech add-on case/bluetooth keyboard, so 
one is not forced to a touchscreen keyboard for most uses.

I am not expecting responses on-list, but any assistance/advice would be 
most appreciated.
