Pulse can be used on several Smartphone.
I would like to know if we can use host checker to validate an Iphone or BlackBerry or even android device?
Can we check for example a serial number, or something that can identify the Samrtphone as a corporate device?
I don't know the answer to that question but just want to clarify something.
Pulse for Remote Client Access is available on iPhone/Android. So your question would only apply (at this time) to those platforms (and possibly only to iPhone since Android is still running under core-access).
Pulse Mobile Security client is available on several other platforms, including Blackberry, but does not interact with HostChecker.
Host Checker / Cache Cleaner features are not supported on Android/iPhone
