                      Registration Statement on Form S-1 (File No. 333-132080)

Dear Mr. Lee:

     Pursuant to Rule 461 under the Securities Act of 1933, as amended,
Synchronoss Technologies, Inc. (the "Company") hereby requests that the
effective date of the above-referenced Registration Statement on Form S-1 (File
No. 333-132080) be accelerated so that the Registration Statement may become
effective at 4:30 p.m. Eastern Time on Wednesday, June 14, 2006, or as soon
thereafter as practicable.

     The Company hereby acknowledges that:

         o     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;

         o     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

         o     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.

     By separate letter, the underwriters of the issuance of the securities
being registered will join in this request for acceleration.


               Thank you for your attention to this matter.


                                       Very truly yours,

                                       Synchronoss Technologies, Inc.
