Transaction ID question.

Well to start off with a high TID does not work well... So I havent tried it.

But a 32-bit integer is large enough to not cause any real life issues for some weeks and when it does one (read: me) will notice there is no communication available and handle it accordingly...

A pity one wont get a medal for longest up time though ;-)

Happy easter to all of you and "Christos is (truly) risen" for our russian orthodox subscribers (albeit having easter on sunday 12th).

I will try getting into STK, USSD and other service during this easter (not the phonebook however).
