H1B revoked by employer by HR error

I worked for company A, and recently was conveyed by the employer that the H1 B was revoked some months back, as a result of HR dept error. The H1 was approved but later revoked. Currently I am on H4 (applied for H4 with receipt number), Other employer is willing to change the status from H4 to H1B. Do I come under the H1B cap exempt , or do I have to wait till next year 2013 fresh H1 B cap quota starting in April.
