Is it possible on iPhone to create a data connection by specifying the SSID of the network?
Is it possible from application to check the signal/availability of the network with specified SSID?

What you're trying to do is sadly not possible without the usage of private (undocumented) API-s. Hopefully Apple will provide this kind of functionality (with users permition) though i don't think this is bound to happen soon.
If you want to research this topic further the first place to check would be iphone-wireless - the home of Stumbler which shows a nice usage of MobileApple80211.
