Please urgent help for H1B Transfer

[Spring2012]

While my H-1B renewal is under review at USCIS and got a RFE, can I change my employer? The current employer submitted for renewal of the H-1B prior to the petition expiry date of August 20, 2011.

Thanks in advance

Similar question:

Employer A applied for H1-B extension (7th yr with I-140 approved) and while in the midst of decision I want to change employer. Can new employer B apply for H1-B.

If I were to travel outside country next month after changing employer.. hoping I get a response for H1-B extension... can I use the extension H1-B for my stamping (Visa stamp expired) OR do I need the changed employer H1-B for stamping... which I don't think would be in my hand in a month (unless premium process).
