Funny, I was just reading about that, yesterday. What is the difference between the regular app and the gmail-specific app?
I'm not quite sure what you mean by "the regular app" so if you can clarify that I would appreciate it.
OneMail is a new product that was designed to address the ability to access your actual email account directly on your smartphone/tablet via a low bandwidth satellite phone. A data call on an Iridium handheld phone or GO runs at about 2.4k, therefore loading a web mail site or standard email client is impossible. Even with Globalstar at 9.6k, this is a challenge, and the IsatPhone is the slowest of the bunch at about 1.2k. OneMail is compatible with all of the phones and accesses your gmail account in a very optimized way. It only downloads the headers of new emails initially which requires very little overhead, but then allows you to pick and choose which emails to actually download. The app automatically initiates and ends the data call on the sat phone as soon as it is done downloading/uploading, so the airtime used for this process is minimal. Right now, it will only work with gmail, but in the near future it will expand to many other email providers. Even if you don't have a gmail account, you can still make use of the app by starting a gmail account and auto-forwarding from your regular account to that account while you are out in the field. Eventually, the app will be comprehensive enough to access nearly any type of account directly.
