Beeper Mini – iMessage client for Android▲1,521
Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system.

It can also be improved; I know BLE is not _that_ effective under rubble. If you have any feedback or can contribute, don't hold back.
