Dear Ms. Wray:

     Synchronoss Technologies, Inc. (the “Company”) hereby requests that the Securities and Exchange Commission (the “Commission”) take appropriate action to make the above-referenced Registration Statement on Form S-3 effective at 4:30 p.m., Eastern Standard Time, on April 14, 2010 or as soon as possible thereafter. In connection with such request, the Company hereby acknowledges that:

	•		should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing;
	•		the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and
	•		the Company may not assert the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

     The Company hereby authorizes Marc Dupré of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, our outside counsel, to orally modify or withdraw this request for acceleration.
