If any store, then F-Droid. But for now, why not just grab the most recent compiled WIP-Release from here and give it a shot? https://github.com/SecUpwN/Android-IMSI-Catcher-Detector/rel...
Also, as much as I appreciate your comment just to find this thread later on, this is NOT the official discussion of the App. I HIGHLY recommend just starring the GitHub and (if you have balls) contribute to it's success by submitting pull requests. Thanks for listening, spread the link to the GitHub in all social media and places where potential developers and good Hackers hang out! ;-)
Here is the best hint I can give you: LEAVE YOUR PHOEN AT HOME when you really have to participate in demonstrations! The main reason why the use of IMSI-Catchers, Stingrays and alike is such a popular tactic for law enforcement agencies is because people are not SMART ENOUGH to think ahaed and leave their phones at home!
No solution for you? Well then, at the very least make yourself your own signal blocking pouch to fully block all Silent SMS: www.killyourphone.com
This project aims to warn users if the ciphering is turned off and also enables several other protection-mechanisms. Since it is under constant development, they are constantly searching for testers and security-enthusiastic developers with balls. Don't be shy, feel free to contribute, in any way you can on GitHub: https://github.com/SecUpwN/Android-IMSI-Catcher-Detector

On the software side of things the closest you can get is a phone running OsmocomBB. That only runs on some dumphones and is not useful from a user perspective, it is only for research. For smartphone software, the closest you can get is a phone running Replicant. That still has all the embedded proprietary software; baseband OS, bootloader, wifi/bluetooth/camera firmware etc.
On the hardware side of things, we have no ASICs with libre designs. I think there have been some cases with libre designs but none manufactured in large quantities. There are myriad patents covering various hardware processes, instruction sets, CPU stuff etc. See bunnie's talk about layers of openness and the Novena laptop for more on this.
RMS uses other people's phones, he doesn't have one himself, mainly due to the network side of things though.

The "source" for a bitmap image (PNG/BMP etc) can be a vector image (SVG, PostScript etc) or maybe a multi-layer bitmap image (Gimp, Photoshop etc). The "source" in "open source" refers to that the files that were transformed into the files in question are available under a libre license, not what kind of file format or language they are represented in.
