Has anybody else had stability issues. My SGS appears to restart itself every so often now and it keeps scanning the media and saying my SD has been removed. I was thinking of going back a step or two (maybe 2.2.2, as this has been the smoothest running version so far for me), but i'm getting a bit fed up of constantly having to reapply my apps etc. I tried to root my phone via one of the step by step guides on here but to no success. Sorry if i'm being a pain, but as stated earlier i'm quite new to this and do want to learn.
