after update, the site can't not login in~

after update to 1.0 RC2, the site can't not login in~
How to fix it and I am using the joomla 1.5.23 and i am using the Jomsocial hellome login in module!

Do you use RC2 or RC2.1 (was released next day after RC2 and contains fix for login issue).

Hi~
So,when will have the RC.1?

Hi - yes I found that when trying to login as admin via iphone/mode version that 130 sessions were instantly created for admins! and that I could not log in as a user - I am using 2.1. Removed these via cPanel and reinstalled your (great) component.

I don't need iphone login but that's what happened - thanks

I am sure your id and password is not stored in database that's why he is not recognising you.

Given I may have mistyped the login as a 'user' but I guess my biggest concern was as per my post above.
130+ ADMIN logins in the space of a few seconds - eg; there is a LOOP somewhere - I manually removed them all via cPanel
