mail issue with iphone software 2.0 and jailbroken phone

Until a recently my phone was jailbroken, in order to run apps like Twinkle and Go. Earlier today I upgraded to the leaked 2.0 firmware. The upgrade itself went without a hitch, and everything seemed to be working. That is until I tried to start the Mail app. It immediately closed. It seemed like Mail was crashing due to permissions or settings. Here are the steps I tried that failed:

• Disabling the account
• Deleting the account
• Re-upgrading the phone
• Running Setting Reset on the phone
• Running Full Reset on the phone
• Attempting to downgrade to 1.1.4 (the downgrade failed every time)

Here’s what worked:

• Re-upgrade the phone. don’t restore from a back up or select setup new, yet
• open Terminal.app

  cd ~/Application Support/MobileSync/Backup
  cd <newest folder here>
  grep Accounts *|cut -d’ ‘ -f |xargs rm
  

• Reconnect the phone and restore the backup you just messed with

I am currently enjoying a fully working firmware 2.0 phone restored from that backup. I did loose my alarm clock and weather settings, but those aren’t very hard to fix at all. Hope that helps.
