iPad custom app - file sync

[kapilok]

Hi Synthesis community,

I need help with sync from iPad custom app.
The scenario is ...
Multiple users can modify the same file (assume custom XML) offline on iPad, then sync to the server. I plan on using the SyncML standard to achieve this.

Please advise how to solve this problem with Synthesis products.
If iPad is not supported, go ahead and advise solution with iPhone / Android.

Thanks,
Kapil
