Gmail password problem iPhone 3G

After reading all the stuff about Mat Honan getting hacked, I decided to turn on 2-step verification and change my gmail password.  This has proved disastrous.  I can no longer acces my gmail through the native mail app on my iPhone.

I looked through all the forums and apparently the 2-step verification was a part of the problem.  So, I turned that off.  Guess what...I still can't get on.  But only on the native mail app on the iphone.  If I use Safari, I can log in fine on my iPhone.  I can log in fine here on my computer.  It's just in the mail app.  Any ideas anyone?

I've deleted the account all together and tried to re-add the account.  I've reset network settings (out of frustration, not thinking that would actually help).  I've done all I can think to do.  Please help!
