2 Quick Qs about OS X beta updates

Hi all-

I have 2 questions about beta updates to OS X.

1. If I install a beta OS X lion update (like 10.7.2), will I be able to use software update to install the actual release version of 10.7.2 when it become available or will I be stuck using betas of OS X indefinitely?

2. Is there anyway to uninstall a beta OS X update?

I am helping a friend develop an iphone app and have my UID registered. The reason I am asking is because I need the lion update to use icloud iTunes Match.

Are the updates usually stable?

Do I have the option to downgrade?

When the actual update is released, can I upgrade to the general public release or am I stuck on the beta?


thanks.

i should also add that I do not have a test mac, I have everything backed up with time machine but if there are usually lots of problems with the betas I won't upgrade. I only need this one beta for itunes match, beta updates for me won't be a regular thing. I want to get back on apple official updates once ios5 and itunes match are officially released
