H1B status changed from RFE to Acceptance stage


My petition was filed under new regular H1b on 11th may 2012. Later I got my receipt number in July. Till yesterday my status was showing in initial review. A day after it showed me RFE, but on the same day when i checked the staus again it shows me acceptance. How did it go back? Is there anything wrong? I am just very curious. Anyone faced the same issue??

Some time it happens for few people but you will have your correct status after two or three days.
