Phone will return to activation screen, but don't panic, just wait. iPhone should automaticly restart after almost a minute. When the phone starts again, it should no longer say Slide to emergency, but rather Slide to Unlock. This means it was successfull!
I've had a few reports of the emergency slider not changing to the unlock slider. The best suggestion so far has been to keep the iPhone connected to the computer and make sure its detected in iTunes. Otherwise it seems to work if you retry installing AppSnapp till it works. Don't know what the issue is exactly (maybe a server load issue) but if it doesn't work immediately then try again.
