Wow...after a brutal review process and back and forth negotiations with Apple they have finally allowed the release of version 3.4 of the iPhone app. This has a significant rewrite of the Humidor Sync process. This should hopefully resolve the issue reported to date. It also now allows for sync'ing to more than 1 device - like Web to iPhone and Web to iPad.
There's some other minor enhancements as well - like showing a tally of total cigars in your collection and totals for each humidor as we have on the site.
Anyone who reported Sync issues should update to this version and hopefully your issues will go away.
For those wondering, the Android update with the same fixes and enhancements is about a week away.
Cheers!
