As stated already... wiping completely then installing .37 will fix freezing and lagging issues.. as for the camera.. its a small price to pay while waiting for the official release.. i have been running .37 for 2 days and only issues have been the entering text on the browser (which happens rarely) and the dum camera..

but the os runs much faster and works great... for those wanting to keep the today plus theme.. don't wipe out your bb and just upgrade.. when i first updated my today plus theme stayed, but when i blanked it today and installed fresh.. it will not install..
