OFFLINE APPROVAL - SRM 7.0 integration with Mail Client on iPhone

Hey SRM Gurus,

It is my understanding from past experience that SRM 5.0 (offline approval) integrated well with MS Outlook on iPhone.

However, is the integration supported on SRM 7.0? I would assume so, however, just want to make sure it is supported. Has anybody done it recently- either with MS Outlook of IBM Lotus Notes?

An early response is greatly appreciated.

Thanks,

Sai
