Android :: Same Code & Phone Models - Inconsistent Results

I recently added a feature to my app that allows the user to send a report via a message chooser (all have chosen gmail) that helps mitigate the fact that I don't have all the physical phones to test on. Execution worked as expected on my G1 and the emulator, however, to my horror as users began sending them in most of them were incomplete! Pseudo-code of what I am doing is as follows: On my phone and the emulator, all of the packages are inserted into the email. However, most of the emails I get, even from the same exact phone model/carrier/OS version, only contain "Text1". Users that have automatic signature insertions even have that at the bottom, so it's not that the email is being cut off somehow, it's that size is apparently 0. That is the only thing I can think of. Every once and a while I will get a full email though. This frightens me because what other APIs run fine in my testing but not user phones? What's going on here?
