I used to keep most of my contacts (even local) phone numbers with international prefix before phone number itself. like +48 600600600.
Since I've updated my two Pre 2 phones to webOS 2.2.4 (both using different local carrier provider) I'm unable to call any number with international prefix, such +48. It doesn't matter if use the number from Contacts or dial it manually on Phone pad. when I call +48 or 0048 I always can hear from carrier provider is "calls with single 0 are not available, please choose the right number with 'plus' or "double zero' in the beginning". So to make calls I had to remove all international prefixes from my contacts.
But what I discovered later is that when I use ++48 or 000 as international code - than it's working - strange!
I checked my Regional settings and even change them to completely different country/language - it didn't help. My suspicion is also that maybe some of my patches or Applications installed makes that mess, but which one?
So what is the case? Maybe someone else have same issue and already solved it? As I have some friends with Palm Pre 2 devices I check with them, but unfortunately this "international prefix" issue happened only to me. But to both my Pre 2 devices so it could somehow happened also to some of you guys...
