I have multiple browsers on my EE and they all occasionally crash. If I needed to rely on browsing (for me the crashes are an inconvenience but no big deal) and did not need Android 2.2 for apps I would go back to Dingo. Your e-ink side should function fine (maybe a tad slower and without the rotate function) and the native browser should be stable. You will only have the K9 email, but I doubt that's a stopper. Just be sure your apps will run with Android 1.6 and that you've backed everything up!
Good luck, and I hope you make friends with your eDGe again!
