Today, I will show you how to add Flash playback to your jailbroken iPhone 4 in three easy steps using an app called Frash by Comex.
Step 1: Launch the Cydia app on your jailbroken iPhone 4 and tap Manage.
Step 2: Add the Source for the Frash app by tapping Sources, Edit, and Add. A dialog opens reading Enter Cydia/APT URL immediately following the provided “http://” enter repo.benm.at and tap Add Source. Once this is completed tap Return to Cydia.
Step 3: Install Frash by tapping Search and enter Frash as the search criteria. Tap Frash – Flash for iOS then tap Install and then Confirm. Frash will begin to install taking only a few minutes or less. Once it is completed tap Return to Cydia.
Frash is now installed on your iPhone 4 and ready to go. Launch Safari and navigate to http://www.adobe.com to try it out. Initially you’ll see a gray place holder labeled Flash for the flash content on a web page. If you tap it you’ll see the flash content start to play.
The content that I tested and experimented with was either hit or miss as far as the results went during testing. It worked some of the time and often did not work at all or crashed, but it is still some what useful for Flash games and videos.
Normally, there is an option called Frash Toggle for SBSettings which is an app that will allow you to toggle Frash on and off. I usually recommend installing that app also, but the currently available version only works on iOS 3.2. You’ll see a warning from Cydia about this prior to installing it. Hopefully the author will find some time to update the app to iOS 4.1 so you could install it yourself later. I skipped it for the time being with the hope of keeping the jailbroken iPhone 4 stable.
