I have an iphone 4s with 5.0.1. I just finished restoring my phone to factory settings and I didn't utilize my backup file. Before the restore I didn't hv this problem. I'm using gmail through exchange and i hv followed all the directions given to resolve this annoying ass password issue but to no avail. I cannot get my contacts, email or calendar and I'm beyond frustrated. I hv even deleted the acct then re-added it after I did the captcha verification and turned on the two-step verification. PLEASE HELP!
