It looks like Allstate has joined the Android revolution with their new mobile app for Android devices. With the Allstate Mobile app, you can view your account information, claims, find an agent, or even start an accident report with their accident support option:
After a collision, follow the step-by-step accident checklist, record driver and witness info and capture photos at the scene with the Allstate® Mobile accident support features.
Allstate Mobile is a free download for Android 2.1 and higher. If Allstate isn’t your carrier, maybe the apps from Progressive, State Farm, or USAA are up your alley.
