Yup. I just tested ~~the fdroid~~ signal (the non-google-play apk from signal's web site) with orbot (a tor VPN for android) and verified it works correctly for text messaging. As you say, using a bridge should make it difficult for iran to block. I wouldn't be surprised though if voice/video was too high latency or doesn't work at all. https://mobile.twitter.com/sporksmith/status/135738175783478...
